The difference between alumina ceramics and corundum

Highpurity alumina ceramics are ceramic materials with an Al2O3 content of more than 999 Because their sintering temperature is as high as 16501990 ℃ and the transmission wavelength is 1 to 6 μm they are generally made into molten glass to replace platinum crucibles use its light transmission It can be used as a sodium lamp tube and can be used as an integrated circuit
