High purity alumina products can withstand very high temperature under reducing, inert or high vacuum condition. They remain good chemical resistance under high temperature, and have excellent wear and abrasion resistance. Alumina products can withstand up to 1750 ^oC.

Note: Alumina products are sensitive to thermal shock. Try to warm up the furnace chamber slowly. A heating rate between 150 ^oC~300 ^oC/hour is recommended for the first 1-1.5hours, so that the alumina products can be evenly heated to reduce the impact of thermal shock.
