shaped refractory bricks,
high alumina brick
Phosphate Bonded Insulation Refractory Fire Bricks with Size 230x114x65mm
Excellent thermal stability phosphate bonded high alumina brick for industrial furnace 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 efractory brick also include kaolinitic clays, which are roasted to create an unique combination including mullite and also synthetic alumina.
