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, industrie chimique, matériaux de construction, céramique, verre, et d'autres industries. Par rapport aux matériaux d'isolation traditionnels, zirconia bubble bricks have a higher refractory temperature, better thermal stability, and longer service life.
