A polycrystalline sintered body of corundum with a dense internal structure! A refractory material with high chemical stability.
"Sintered alumina" is a refractory raw material that excels in wear resistance. Calcined alumina is pressure-formed using a briquetting machine, and after drying, it is sintered at a high temperature close to its melting point (2,050°C) in a rotary kiln. It is a polycrystalline sintered body of corundum with a dense internal structure, boasting a high purity containing more than 99.5% Al2O3. 【Features】 ■ High mechanical strength ■ High thermal conductivity ■ Strong against thermal shock ■ High melting point ■ High electrical insulation *For more details, please refer to the related link page or feel free to contact us.
