Application of Zirconium Hollow Spherical Brick
Zirconium bubble bricks are mainly used for heat preservation and thermal insulation of high temperature furnaces, and are widely used in various furnace equipment in metallurgy, chemical industry, production of building materials, ceramics, glass and other industries. Compared to traditional insulation materials, Zirconium bubble bricks have higher refractory temperature, better heat resistance and longer service life.
