Product Introduction

Yttria(Chemical Formula:Y2O3)white, slightly yellow powder,Insoluble in water and alkali,soluble in acids. Mainly used for producing microwave use magnetic material and important material in military project (single crystal, Yttrium iron garnet,Yttrium aluminum garnet etc. composite oxides). also used as optical glass, ceramic material additive, hi-lite phosphor powde in large screen TV and other kinescope coatings, etc.

Raw material of rare-earth composit oxide solid solution ceramic thermal field designed and producing by Fangming Newm self selected standardization,technological process,after melt under 2850 deg.cel., formed stable solid solution transparent large crystals,crush into grain, powder, instantly blow the bubble hermetic thermal isolation ball by using high pressure airflow, the whole process of combined program from raw material, technology, to second time combined sintering products and application, have laid the basic advantage for super high-temp. artificial crystal thermal field system Fangming Newm produced.

Obvious advantages of Thermal Field

1.Can directly act on heater radiation.Applied in above 100-120kg grade KY method big-size crystal Grower, the excellent comprehensive performance has been reflected.Solid Solution Ceramics is super low thermal conductivity material, as super low thermal conductivity matched high reflecting rate of metal screen, can further improve the accuracy of thermal field control and temperature gradient, meantime improve the crystal growth yield, bring down power consumption, bring down the metal thermal field invest and working cost.

2.In the nitrogen, vacuum environment, the long-time working life of rare-Earth Composite Oxide Solid Solution Ceramic Thermal Field is below 2650℃, has excellent repeated use performance, avoid cracking phenomenon of ceramic thermal field caused by repeated use.

3.As thermal field in crystal grower, it is the best working effect, many times repeatedly working and working life reached 3 years recycle period in crystal grower a present, shorten 25% of the crystal growth period, bring down 40% of energy consumption, have the one time oxygen release and do not store oxygen, 0 release, do not corrode melt parts in the furnace, the only Rare-Earth Composite Oxide Solid Solution Ceramic Thermal Field .

4.It is one kind of recyclable material, recyclable material can be secondly used in producing ceramics in other high-temp. industry through special process, is one kind of green, eco-friendly, energy-saving, down-consumption in the whole production process, and recycling resources ecological chain product.

Key Technology

Rare-Earth Composite Oxide Ceramic Thermal Field 6 Unique characteristics
1.Under vacuum, protective atmosphere,air conditions, working temp. reach 2650 deg.cel.
2.Under vacuum, above 1800 deg.cel., oxygen of ceramic thermal field material release 1 time and continuous keep on at room temp.
(delay and protecting working life of other metal part in thermal field )
3.Repeatly raise and lower temp.cycle working life reach 3 years.
(Comparing metal thermal field, working life risen by 6 times.)
4.Example for 120kg grade crystal using thermal field, shorten 25% of growth cycle ,saving power consumption above 40%,comparing metal material.
5.Break through the bottlene of large-size crystal growth thermal field, realize crystal large-size mass production.
6.Recycle for ceramic thermal field working more than 3 years, through technology process, produce high temp.ceramic products as flow control refractory in metallurgy. (Achieve green, Infinite resources recycle industry system)

Vacuum environment and after deoxidation condition

Rare-Earth Composite Oxide Solid Solution Ceramic Material works for 24 hours in 2300 deg.cel. vacuum environment and after deoxidation. No size changes, no volatilization, no expansion or shrinkage, in 2300 deg.cel. environment,no agglomeration or melting,no deformation or crack, etc. problems appear. The oxygen contained in material has been released completely, and in heating in room air or vacuum environment,not any oxygen absorption behavior occurs.

Fangming NewM Long-Term Goal

Based on cognition of Rare-Earth Composite Oxide Solid Solution Ceramic Material,mastery of key technology and optimization of ceramic thermal field design,Fangming Newm are willing to make Long term strategic cooperation with the crystal equipment manufacturer, crystal enterprises, supply the exceed expectations optimization program and product performance for the clients, jointly promote the continuous development and innovationworld of the world artificial crystal industry.
