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.
