Calcined zinc oxide is a commonly used chemical additive with large bandgap and exciton binding energy, high transparency, and excellent room temperature luminescence performance. It is widely used in liquid crystal displays, thin film transistors, and light-emitting diodes in the field of semiconductors.

Medical zinc oxide has deodorization and antibacterial functions, and is often added to cotton fabrics, rubber, and food packaging. The calcined zinc oxide added to food not only has a certain anti-corrosion effect, but can also serve as a zinc source to supplement some essential zinc elements for the human body. Some sports bandages also incorporate zinc oxide to prevent athletes from developing soft tissue damage during exercise.

Zinc oxide in the silicate industry is an additive in cement, which can effectively reduce the hardening time of cement and greatly improve its waterproof performance. In the production of glass and ceramics, calcined zinc oxide can be used as a flux to effectively reduce the sintering temperature of glass and ceramics.

Calcined zinc oxide in the electronic field has a high energy band gap at room temperature, so it is commonly used to manufacture laser diodes and light emitting diodes. Zinc oxide has great exciton binding energy, and its luminescence brightness is very high. This product has been applied in solar cells and LCD displays.
