Description
Industrial Grinding Zirconia Ceramic Ball Bead
Properties of Zirconia Ceramic Ball Bead:
1.Excellent wear resistance
2.High impact resistance
3.Very high resistance to crack propagation, high fracture toughness (6.5 to 8 MPam1/2)
Zirconia (ZrO2)ceramic is an extremely refractory material. It possesses excellent chemical
inertness and corrosion resistance at temperatures well above the melting point of alumina.
Advantages:
1.High temperature resistance
Zirconia ceramic ball bead can maintain their stability and strength at high temperatures,
so they can be used in applications in high temperature environments, such as high temperature
reactors and furnace linings.
2.Anti-corrosion
It has excellent chemical stability and anti-corrosion properties, and can resist the erosion of corrosive media such as acids, alkalis, salts,
so they can use for the treatment and separation of corrosive media in the chemical industry.
3.Wear resistance
Zirconia ceramic have excellent hardness and wear resistance, and can use in abrasives,
4.Insulation
They have good insulation properties and can use in electrical insulation materials, electronic components and other fields.
