Industrial Ceramic Intriduction
Advanced ceramic washer is the most widely applied and cost effective technical ceramic material. ceramic washer offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1750 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.
Ceramic materials are mostly oxides, nitrides, borides and carbides.Common ceramic materials are clay, alumina, kaolin and so on.Ceramic material is general hardness is higher.
Advantages of ceramic washer:
1. Molding: Isostatic pressing
2. Wear-Resisitance: Approx 10times stronger than common pipes under same conditions
3. Corrosion resistance: Strong acid or alkali resistant
4. Scouring abrasion resistance: Can bear scouring abrasion by large grain material without damage
5. Good fluidity : Smooth surface ensure the free flow of material without blocking
6. Low maintenance cost: Super wear-resistance reduce the maintenance frequency and also the maintenance cost.
