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, industria chimica, materiali da costruzione, ceramica, bicchiere, e altre industrie. Rispetto ai materiali isolanti tradizionali, zirconia bubble bricks have a higher refractory temperature, better thermal stability, and longer service life.
