Application of zirconia hollow sphere brick

Zirconia bubble bricks are mainly used for heat preservation and heat insulation of high-temperature furnaces and are widely used in various furnace equipment in metallurgy, chemical industry, building materials, ceramics, glass, and other industries. Compared with traditional insulation materials, zirconia bubble bricks have a higher refractory temperature, better thermal stability, and longer service life.
