Specifications

Zirconia hollow ball and purity fused zirconia powder by molding, high temperature sintering in the system,

 

Product Description:
Zirconia hollow ball products entirely made of zirconia hollow spheres and high-purity fused zirconia powder by molding, high temperature sintering in the system, there are good high temperature strength and stability of the pore structure for ultra-high-temperature devices lid and other parts of the adiabatic materials, such as IF furnaces, carbon black reactor, tungsten rod furnace, molybdenum furnace. Zirconia hollow ball bricks are insulating refractory products with excellent performance, high temperature, the maximum safe operating temperature of 2200 ℃, acid erosion, good insulation properties, is widely used in metallurgical, petrochemical, electronics, military and other industrial thermal equipment in direct contact with the flame temperature as lining materials, with favorable results.
