FEATURE

It is made of alumina ceramics in different high temperatures, with high purity and controllable size, even granularity, good fluidity,
high MP, stable performace and low electric conductivity. And it is hard to dissolve in acid and alkali.

FINAL
APPLICATION

Widely used in shaping & formless refractory materials wearable Alumina ceramics in high temp., electron device, polishing industry
and luminescent material.
