Zinc Oxide Product Overview

Product Overview

Zinc Oxide (ZnO) is a versatile inorganic compound, typically in the form of a white powder, with broad applications across a variety of industries. It is primarily used in cosmetics, pharmaceuticals, rubber, coatings, electronics, and more. ZnO is known for its excellent UV absorption, antibacterial properties, conductivity, and chemical stability. It is a critical component in many products, providing protection against UV radiation, inhibiting bacterial growth, and enhancing product durability.

Key Product Characteristics

• UV Protection: Zinc Oxide blocks UVA and UVB rays, offering strong UV protection. It acts as a physical sunscreen agent, forming a protective barrier on the skin.
• Antibacterial Properties: ZnO inhibits bacterial growth and has soothing anti-inflammatory effects, making it ideal for treating skin conditions.
• Chemical Stability: ZnO is chemically inert, ensuring long-lasting performance in various environments without reacting with most substances.
• Thermal Stability: Zinc Oxide remains stable at high temperatures (up to 600°C), making it suitable for high-temperature applications.
• Non-Toxic and Safe: It is a non-toxic, skin-safe ingredient used in products such as baby care and sensitive skin treatments.
• Semiconductor Properties: Zinc Oxide’s conductivity and semiconductor properties make it ideal for use in electronics, sensors, and optoelectronic devices.

Applications

• Cosmetics & Personal Care: Used in sunscreens, day creams, BB creams, cleansers, and facial masks for its UV-blocking properties and skin protection.
• Pharmaceuticals: Zinc Oxide is a key ingredient in anti-inflammatory ointments, calamine lotion, and treatments for acne, eczema, and minor skin irritations.
• Rubber & Plastics: It is used as a vulcanizing agent in rubber production, improving strength, wear resistance, and aging properties in tires, footwear, and industrial rubber products.
• Coatings & Paints: In the coatings industry, Zinc Oxide serves as a white pigment with excellent coverage, durability, and UV resistance, used in paints, anti-corrosion coatings, and waterproofing products.
• Electronics & Optoelectronics: As a semiconductor, Zinc Oxide is applied in solar cells, sensors, LEDs, and other optical and electronic devices for enhanced efficiency and stability.

Production Process

• Raw Material Selection: The primary raw materials for Zinc Oxide production are zinc ores (such as sphalerite) or zinc metal.
• Roasting Process: Zinc metal is heated to high temperatures to react with oxygen and form Zinc Oxide. Temperature and oxygen flow are carefully controlled to achieve the desired purity and particle size.
• Grinding & Screening: After roasting, the Zinc Oxide powder is ground into a fine powder and screened to ensure uniform particle distribution.
• Purification: In some cases, additional purification steps are taken to remove impurities and enhance the purity of Zinc Oxide.
• Quality Inspection & Packaging: Zinc Oxide is thoroughly tested for particle size, purity, and UV absorption properties. Upon passing quality checks, the product is packaged and ready for shipment.

Process Flow

The production process of zinc oxide mainly includes a batching system, feeding system, rotary kiln system, slag water quenching system, oxidation cooling system, dust collection and bagging system, and flue gas desulfurization system. The rotary kiln system is the core equipment, where ZnO is obtained through high-temperature oxidative roasting. Depending on raw materials and processes, production methods can be divided into direct, indirect, acid, and ammonia methods.

Theory

ZnO's large bandgap and exciton binding energy contribute to its excellent room-temperature luminescent properties. Meanwhile, its wurtzite hexagonal crystalline structure grants ZnO good electrical, optical, and piezoelectric properties. These theoretical foundations provide a scientific basis for ZnO's applications in multiple fields.
