Item index Max temperature (° c) 1600° c Volume density (g/cm³ ) = 1.67 Apparent porosity (%) = 12.5 Ccs (mpa) = 57 Mor(mpa) = 22 Thermal conductivity (w/m-k) (rt~1000° c) 0.8 Tce (° c-1)(rt~1000° c) = 0.9*10 -6 Crystallinity(vol%) = 1
Fused silica ceramics are manufactured using slip casting which combines elements of ceramic fabrication and powder metallurgy, which are homogeneous and the surface are smooth and less pore. Regarding the customer demands, the surface can be further glazed to shine like jade. Robuster offers a wide product range of fused silica crucibles and trays for numerous applications in corrosive and high temperature environments. Specially quartz trays is a thermal ceramics products for the aluminium & non-ferrous industry. Custom specifications are available.

Artificial graphite Artificial graphite is man made graphite. Manufacturing Method: Main raw material for artificial graphite is high quality calcined petroleum coke powder, add in asphalt as blinder, then add little other materials. Various raw material are well suppressed, and then graphitized in a non-oxidizing atmosphere at 2500~3000. Ash, sulfur and gas content will be greatly reduced after the heat processing. Application: Recarburizer, friction materials, carbon brushes, powder metallurgy. 25kg kraft bag in ton bag
