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, chemische industrie, bouwmaterialen, keramiek, glas, en andere industrieën. Vergeleken met traditionele isolatiematerialen, zirconia bubble bricks have a higher refractory temperature, better thermal stability, and longer service life.
