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, indústria química, materiais de construção, cerâmica, vidro, e outras indústrias. Compared with traditional insulation materials, zirconia bubble bricks have a higher refractory temperature, better thermal stability, and longer service life.
