According to the experimental data, the fire resistance temperature of brown corundum is usually about 1800-1900 degree C, which can be used in harsh environments such as high temperature furnishes. At the same time, brown corundum also has a small coefficient of thermal expansion, good thermal shock stability and other excellent properties.

1. Refractory materials: Brown corundum can be used to manufacture refractory bricks, furnace lining and other high-temperature wear-resistant materials.
2. Abrasive materials: Brown corundum can be used to make abrades, which are used in metal processing, electronic component manufacturing and other industries.
3. Electronic ceramics: Brown corundum can be used to manufacture electronic ceramics, widely used in electronic component packaging, media and other fields.
4. Other fields: Brown corundum can also be used to manufacture thermal tools, automotive parts, fiber ceramics and other products.
