SSiC Crucible & Sagger


Silicon carbide crucible & sagger for heating and reaction of melting and refining metal liquids and solid liquids, ideal for sintering and smelting. It is widely used in steel smelting, chemical industry, petroleum, environmental protection and other fields. Its hardness ranges between corundum and diamond, mechanical strength higher than corundum, high heat transfer rate. An economical device ideal for ensuring the heating material pure and unpolluted, with life expectancy 3-5 times longer than the ordinary ones.

Oustek’s silicon carbide crucible & sagger adapts isostatic pressing, net size sintering and mechanical finishing technique, it produces crucibles & saggers with density up to 3.1kg/m³. Silicon carbide for high-quality refractories adopted so the maximum working temperature reaches up to 1380 ℃ (2500 ℉), with continuous working hours more than 9000 hours.


For melting, heating and reaction of refined metal liquid and solid in metallurgy, chemical industry, glass industry and chemical industry.


  • High strength, high hardness, wear resistance, density up to 3.1kg / m3
  • High attenuation performance, low thermal expansion, high thermal shock resistance, high temperature creep resistance.
  • Chemical stability, corrosion resistance, especially hydrofluoric acid resistance.
  • High-temperature resistance, maximum operating temperature up to 1380 ℃ (2500 ℉)
  • Excellent thermal conductivity can save energy and reduce energy costs
  • Long service life and reduce overall investment cost


Isostatic Pressing

With self-own isostatic pressing equipment, all products use isostatic pressing technology to make the green body uniformly stressed, the density distribution is uniform, and the product performance is greatly improved. There are incomparable advantages when molding complex shapes, elongated products, large-sized products, and precision-sized products.
