Product Specification

Product Description

Magnesium oxide is an inorganic compound with the chemical formula MgO. It is magnesium oxide and an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in nature in the form of periclase and is the raw material for magnesium smelting.
Magnesium oxide has high fire-resistant insulation properties. It can be transformed into crystals after being burned at a high temperature of more than 1000°C, and it becomes dead-burned magnesium oxide (magnesia) or sintered magnesium oxide when it rises to 1500-2000°C.

Advanced electromagnetic grade

Application areas: used for wireless high-frequency paramagnetic magnetic materials, magnetic rod antennas, magnetic cores of FM components, etc. Replaces ferrite. Can be used in the production of composite superconducting magnetic materials, and is also used in the electronic magnetic industry. As a "soft magnetic material". It is also an ideal raw material for industrial enamel and ceramics.

High-purity magnesium oxide

Application areas: High-purity magnesium oxide has excellent alkali resistance and electrical insulation at high temperatures. It has high thermal expansion coefficient and thermal conductivity and good light transmittance. It is widely used as a high-temperature heat-resistant material. In the ceramic field, it is used as a raw material for translucent ceramic crucibles, substrates, etc. In the electrical materials and electrical fields, it is used as a filler for magnetic devices, a filler for insulating materials, and various carriers. When used as a ceramic substrate, the thermal conductivity is more than twice that of alumina, and the loss of electrolyte is only 1/10 of that of alumina. It can also be used as a raw material for high-purity fused magnesia, and can be used as "analytical pure" magnesium oxide in chemistry.

Nano-level

Application fields: Nano-level magnesium oxide has obvious small size effect, surface effect, quantum size effect and macro tunnel effect. After modification, there is no agglomeration phenomenon. It has many special functions and important application value in optics, catalysis, magnetism, mechanics, chemical industry, etc. It has a very broad prospect and is an important new material in the 21st century. Nano-magnesium oxide is widely used in electronics, catalysis, ceramics, oil products, coatings and other fields. The role played in different products is also different. It is used as flame retardant in chemical fiber and plastic industries; high temperature dehydrating agent in silicon steel sheet production, advanced ceramic materials, electronic industrial materials, binders and additives in chemical raw materials; high-frequency magnetic rod antennas in radio industry, magnetic device fillers, insulating material fillers and various carriers; refractory fibers and refractory materials, magnesia-chrome bricks, fillers for heat-resistant coatings, high temperature resistant and insulating instruments, electricity, cables, optical materials and steelmaking; electrical insulator materials, manufacturing crucibles, furnaces, insulating conduits (tubular elements), electrode rods, and electrode sheets.
In the textile field, with the increasing demand for high-performance flame-retardant fibers, the synthesis of new high-performance flame retardants provides an ideal material for the development of functional fabrics. Nano magnesium oxide is often used with sawdust and wood shavings to manufacture lightweight, soundproof, heat-insulating, refractory fiberboard and other refractory materials and metal ceramics. Compared with some traditional phosphorus or halogen organic flame retardants, nano magnesium oxide is non-toxic, odorless, and has a small addition amount, making it an ideal additive for the development of flame-retardant fibers. In addition, nano magnesium oxide has strong cleaning and corrosion inhibition capabilities for fuel oil, and has a good application prospect in coatings.

Feed grade

Adding 50 to 90 grams of magnesium oxide to dairy cow feed daily or adding 0.5% of the concentrate can not only supplement the lack of magnesium in the diet to prevent the occurrence of magnesium deficiency, but also is an excellent rumen buffer, regulates rumen fermentation, and can increase the absorption of milk synthesis precursors by the mammary gland, thereby increasing milk production and milk fat rate. According to foreign reports, adding 0.5% magnesium oxide to the supplement of concentrated feed for dairy cows can increase milk production by an average of 1.6 kg, increase milk fat content by 0.145 percentage points, and help increase feed intake. ?Adding magnesium oxide to dairy cows' diets can prevent heat stress. Magnesium ions can work together with sodium ions and potassium ions to maintain the balance of osmotic pressure inside and outside cells, alleviate the cows' response to heat stress, thereby increasing the cows' feed intake in summer and maintaining milk production. In addition, it is recommended that in the case of heat stress, the amount of magnesium oxide in the diet should be increased to compensate for the loss of magnesium in the body, so as to ensure and maintain normal milk production. Both dairy cows and beef cattle have a good balance mechanism to deal with excess magnesium ions, so an appropriate increase in the amount of magnesium oxide will not cause adverse effects on cattle.
The symptoms of magnesium deficiency in dairy cows are: first, the cows' appetite decreases, their movements become slow, and they become lethargic. As the disease worsens, the cows' gait becomes stiff and their steps shake. Moreover, the cows become nervous and irritable, and their muscles tremble significantly. If it continues, the cows become completely paralyzed and spasmodic. If not treated in time, it will cause death. In addition, magnesium deficiency will reduce the digestibility of nutrients and lead to a decrease in milk production in dairy cows.
When ruminants such as cattle and sheep are grazing, it is important to ensure that their food contains enough magnesium to prevent them from convulsing due to magnesium deficiency. Usually, this convulsion is caused by cattle or sheep eating magnesium-deficient grass in cold weather. There are two most common methods to increase magnesium in livestock feed: one is to mix magnesium powder with syrup and add it to the feed; the other is to add lightly burned magnesium powder directly to the purchased feed. Magnesium deficiency is more common in beef cattle and sheep than in dairy cows. This is because the amount of concentrate in the diet of dairy cows is relatively large, while the amount of concentrate in the diet of beef cattle and sheep is relatively small.
The amount of magnesium oxide added to the diet of ruminants is 0.5% to 1.0%.
Poultry
Newborn chicks can only survive for a few days when fed a diet completely lacking magnesium. When fed a low-magnesium diet, chicks grow slowly, become lethargic, pant, and breathe rapidly. When frightened, they will show short-term convulsions, and finally lead to temporary coma or death. According to experiments, the growth rate of broilers fed a diet containing 200ppm magnesium is reduced by 80% compared with a diet containing 600ppm magnesium.
For laying hens, egg production will drop rapidly when magnesium is deficient. Low blood magnesium causes a large amount of bone magnesium to be used, eggs become smaller, eggshell weight becomes lighter, and the magnesium concentration in yolk and eggshell decreases. Studies have shown that the thicker the eggshell, the higher the concentration of magnesium in the eggshell, which shows that appropriately increasing the magnesium concentration in the laying hen diet can improve the quality of the eggshell and increase egg weight.
Usually in production, depending on age, breed and poultry, the magnesium concentration of commonly used poultry feed is between 0.15% and 0.22%.
Pigs
Due to the continuous improvement of pig breeds and the continuous increase in productivity, the nutritional needs of magnesium should be increased accordingly. Magnesium ion deficiency will greatly increase the mortality rate of piglets. Magnesium deficiency can cause pig stamping, which is manifested by the pig repeatedly lifting its hind legs as if it is stamping in place when standing. For sows, magnesium oxide is widely used as a laxative to prevent stress syndromes such as oversensitivity and tail biting in penned pigs.
Recent studies have also shown that adding magnesium oxide to pig diets or appropriately increasing the concentration of magnesium in diets can improve the quality of pork. Feeding growing and finishing pigs with a diet supplemented with magnesium oxide can improve growth rate and pork quality, including the pH value and color of pork, and reduce PSE pork.
Depending on the growth stage, body weight and production purpose, the magnesium concentration of pig feed commonly used in the feed industry is 0.13% to 0.27%.
Freshwater fish
Freshwater fish need to be appropriately supplemented with magnesium in the feed because the amount of dissolved magnesium in water is insufficient.
