Hollow zirconia sphere bricks are fabricated by sintering of high temperature using

Fused stabilized hollow zirconia sphere as starting material , via molding. They have

Many advantages, such as high temperature resistance (max. Usage temperaturee2200),

High strength , good thermal insulation, various acid-base erosion resistance and

Thermal shock stability. They are widely used in super-high temperature kilns

Of mid-frequency furnace, military and civil ,

Scientific research, refining of high-melting point metals , l

Aser crystals, quartz glass and electron field of tungsten and

Molybdenum industry.
