Production Details

Xintai Magnesia Zirconia Bricks are manufactured using high-purity fused magnesia and synthetic magnesia-zirconium sand as raw materials. The production process includes:

Raw Material Selection: Carefully selected high-purity magnesia and zirconia sand ensure superior chemical and thermal stability.
Mixing and Grinding: Raw materials are homogenized to achieve uniform particle distribution for consistent brick quality.
High-Pressure Molding: Bricks are formed under high-pressure to ensure dense structure and excellent mechanical strength.
High-Temperature Firing: The molded bricks are fired at ultra-high temperatures to achieve full sintering, low porosity, and high load softening temperature.
Quality Control: Each batch undergoes rigorous testing, including bulk density, cold crushing strength, porosity, thermal shock resistance, and permanent linear change on reheating.
