Production Techniques

1. Direct Method: Using zinc concentrate as raw material, it undergoes high-temperature oxidation roasting followed by coal reduction to zinc vapor, which reacts with hot air to produce ZnO.
2. Indirect Method: Melting zinc ingots in an evaporation crucible, heating to vaporize, and reacting with air to oxidize, then cooling and collecting with a cloth bag to obtain the product.
3. Chemical Method: Reacting zinc oxide secondary material with ammonia water and ammonium bicarbonate, evaporating to obtain basic zinc carbonate precipitate, and then calcining to obtain ZnO.

Theory

ZnO is an n-type semiconductor where electrons in the valence band can absorb energy from UV light and undergo transitions, thereby absorbing UV light. When the particle size of ZnO is much smaller than the wavelength of UV light, it can scatter UV light in all directions, reducing the intensity of UV light in the direction of irradiation.
