Application of alumina crucible and ceramic boat:
It is used to make TV powder, phosphor, rare earth materials, precious metals and an ideal roasting container to roast high, medium and low ceramic capacitors NTC, PTC piezoelectric ceramics and lithium cobalt oxide, lithium manganese oxide powder.
Alumina (Al2O3) is a hard, chemically resistant material and has the ability to withstand very high temperatures
in aggressive environments. CS ceramic offers Alumina with various purity levels, including 99.8% and 99.0%.
The level of purity, grain size, and density required is dependent on the rigors of the application and the
component configuration.
