Applications of Zinc Selenite
Colorants and modifiers for ceramics and glazes
Industrial-grade Zinc Selenite can provide unique red hues for ceramics and glazes.Furthermore, it can promote the processability of the glaze and the physicochemical properties of the glaze surface.Not only does it present a visually appealing appearance, but the product is also sturdy and durable.
Clarifying and decolorizing agents for the glass industry
Industrial-grade Zinc Selenite plays two roles simultaneously in glass manufacturing:
Physical function: Clarifying agent —— removes tiny air bubbles from the molten glass, improving the transparency and appearance of the finished glass product.
Chemical and optical effects: Decolorizing agents —— neutralize iron impurities in the glass raw materials, producing a visually white or colorless effect.
Industrial-grade Zinc Selenite is widely used in glass products that require extremely high transparency and color purity, such as optical glass and crystal glass.
Raw materials for the preparation of functional materials
- High-purity Zinc Selenite is the core raw material for extracting zinc selenide.Zinc selenide is a key functional material for manufacturing top-tier infrared optical materials.The resulting infrared optical materials will be used in fields such as infrared imaging systems and high-power lasers.
- Zinc Selenite is a raw material for transparent conductive films (a thin film material that possesses both high optical transparency and good electrical conductivity).It provides an important source of selenium and zinc.
- Electronic-grade Zinc Selenite is a raw material used in the production of zinc selenide buffer layers in thin-film solar cells.Ultra-high purity and extremely low impurity levels ensure high efficiency and high stability of the battery.
