1. Ceramic manufacturing: High temperature alumina is an important raw material for manufacturing ceramics, which can be used to make daily necessities such as ceramic bottles, bowls, and plates. Due to its high temperature resistance, wear resistance, and corrosion resistance, it is also widely used in the production of refractory materials such as refractory bricks, refractory castables, and ceramic fibers.

2. Electronics industry: High temperature alumina is an important material for manufacturing electronic components, such as integrated circuits, capacitors, resistors, etc. It has excellent insulation performance, thermal conductivity, and mechanical strength, which can protect electronic components from external environmental influences.

3. Lighting industry: High temperature alumina is widely used to manufacture reflectors and lenses for lighting equipment such as high-pressure sodium lamps and metal halide lamps. It has high reflectivity and excellent high temperature resistance, which can improve lighting effect and energy utilization efficiency.

4. Chemical industry: High temperature alumina is used as a catalyst and catalytic carrier for manufacturing chemical reactors, catalyst beds, and catalyst carriers. It has high surface area, good chemical stability, and catalytic activity, which can improve the efficiency and selectivity of chemical reactions.

5. Glass industry: High temperature alumina is an important auxiliary material for manufacturing special glass, such as solar glass, fiber glass, etc. It can improve the thermal stability, mechanical properties, and optical properties of glass, and enhance the quality and functionality of glass products.

6. Medical industry: High temperature alumina is used as a base material for artificial joints and dental restorations
