Sintered silicon nitride tube

Sintered silicon nitride tube

Silicon Nitride (Si3N4) bonded silicon carbide (SiC) material is a new type of advanced refractory materials. Compared with silicon carbide product, the product has characteristics of small thermal expansion, high thermal conductivity, not easy to have thermal stress, good thermal shock resistance, corrosion resistance, extreme cold or heat, oxidation, high temperature creep resistant ability and easily made into products with high dimensional accuracy requirements in line. Silicon nitride combined silicon carbide products have very high strength for normal atmospheric temperature, and it remains almost the same time with the strength and hardness at high temperature 1200-1400C. with the difference of using atmosphere, the maximum safe operating temperature could reach 1650-1750C.

All products are produced to the highest quality standards which means the consistent supply of ceramic components to enable your process to run more efficiently.
All components are supplied with a replacement guarantee. This guarantee provides for the replacement of the component if the service life is reduced because of a fault in the manufacturing process.

Typically we offer a guarantee of 40 days life in service for a riser tube in a low pressure aluminum die casting application, depending on the design. Our experience has shown that the design of the riser tube has an effect on the operational life. We can call on our experience and advise on the design of components to ensure the longest possible life for ceramic parts in your equipment.
