200mm Heat-resistant Ceramics For Industry

Name:200mm Wear-resistant Ceramics For Industry Structure:Polycrystal Size:Customized Alumina content:95% or 99%

Specifications:  

  1.Desirable surface fineness

  2.OEM/OPM Offered

  3.Factory Directly 

Productive  Technology:

     Wear-resistant ceramic is the special corundum ceramic that been sintered under 1800°C with 

the main raw material of Al2O3 and flux of rare metal oxide.Using the high strength organic/inorganic 

bond to felt together, and then grinding to the size as drawing required.

Advantage:

  1.Insulated

  2.Wear-resistant

  3.Resistance to elevated temperatures

  4.Corrosion resistance

      

     We can produce wear-resistant ceramics according to clients' specifications and even  

                          according to molds or drawings provided by the client.
