Product Description

Product description

 

Check brick for cowper stove is made out of a naturally-occurring material known as bauxite.This material include aluminum hydroxide, which is what give the brick such great warmth resistance. High alumina refractory brick also include kaolinitic clays, which are roasted to create an unique combination including mullite and also synthetic alumina. This is where the name “high alumina” stems from.

we always select the highest quality raw material to guarantee product quality.
