Product Description

Refractory balls Alumina Ceramic Ball for Heat Storage
Refractory ball are made from Alpha Alumina and refractory kaolin and produced by scientific formula, shaping and firing at high-temp.

Refractory ball has a lot of advantages, such as:
1) High strength, long use period
2) Chemical stability, it won't react with our materials
3)Good performance of resistance high temperature, resistance high temperature up to 1900ºC
