  • Ceramic Material Supplier - Stanford Advanced

    2021-5-25 · Ceramic material’s poor wettability with molten metals also makes it ideal for metallurgical melting. Recently engineered ceramics are made by oxide, carbides, and nitrides. Alumina, or aluminum oxide, Al2O3, is the most well-known oxide ceramic material and the major oxide ceramic material.
