Silicon carbide - Nitride Bonded Silicon Carbide (NBSC) -- Refractory Tubes


Silicon Carbide Manufaturers/Furnace Brick 


These products are used by a range of customers in applications where heat and wear resistant materials are required.

Silicon nitride bonded silicon carbide products are chosen because of superior wear resistance, high strength, and the ability to handle elevated temperatures (to 1750 degrees C).


NBSC is also resistant to attack by many chemicals and is not wet by most molten metals. In addition NBSC does not react with molten metals or their oxides.

Applications include:

Ceramic kiln shelf,panels,pillars,seperated flame plate,Waste Incineration Furnace Lining,aluminum tank.


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.


Complex shapes can be cast and fired to fine tolerances. The current product range includes riser tubes, thermocouple tubes, heater sheaths, hydrocyclone liners, impeller and pump casing assemblies, pipeliners, and burner nozzles.
