Product Description

Product Description:                                                                                                                                            

Yttrium stabilized wear resistant zirconia ceramic ball high hardness grinding tank universal circle

Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.

Alumina ceramic ball  Alumina ceramics are generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.

Advantages 1. Excellent electrical insulation 2. High hardness 3. Relatively low strength and fracture toughness 4. Resistance to wear and corrosive 5. Excellent thermal stability 6. Resistance to high temperatures 7. High electrical resistivity 8. Good chemical stability and resistance 9. High corrosion resistance
