Цырконіевая бурбалкавая цэгла

Zirconia bubble brick is a kind of high-temperature refractory material, which is composed of zirconia bubble particles and binders. Zirconia bubble particles are a porous material composed of zirconia particles, which have high compressive strength and good thermal insulation performance.

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, хімічнай прамысловасці, building materials, кераміка, шкло, і іншыя галіны прамысловасці. Compared with traditional insulation materials, zirconia bubble bricks have a higher refractory temperature, better thermal stability, and longer service life.
