Zirconia-Mullite Precast Units are high-performance refractory prefabricated components specially developed for high-temperature industrial furnaces requiring excellent corrosion resistance, thermal stability and long service life. They are manufactured from premium zircon sand, mullite aggregates, fused zirconia-mullite and high-purity alumina materials through advanced formulation, precision molding and high-temperature firing processes.

Designed for severe thermal and chemical environments, these prefabricated refractory units combine the excellent properties of zirconia and mullite phases, including high temperature stability, superior thermal shock resistance, strong corrosion resistance and long service life. Compared with traditional refractory bricks and monolithic linings, Zirconia-Mullite Precast Units provide better dimensional accuracy, faster installation and improved structural reliability, making them an ideal solution for critical areas of glass melting furnaces, industrial kilns, heating furnaces and high-temperature equipment.

Luming provides customized Zirconia-Mullite Precast Units according to different furnace structures, operating conditions and customer requirements.
