Product Details


Description of Silica Brick


Silica bricks for HBS are characterized by low thermal expansion, slight residual quartz, lower true density, and good thermal shock resistance at 600℃ and above, high refractoriness, under load low creep as well as regular precise size. 


The main application covers high-temperature zones such as HBS dome, upper stack, and upper checker unit and so on.
