How Are Sialon Ceramics Manufactured?

Sialon ceramics are manufactured by combining a mixture of raw materials including silicon nitride, alumina, aluminium nitride and silica. along with the oxide of a rare earth element, such as yttrium. At times, the silicon is replaced by aluminium with the corresponding atomic replacement of nitrogen by oxygen; this is done in order to satisfy valency requirements. The resulting 'solution' has superior properties, both to the original pure solvent, syalon and to silicon nitride or Si3N4.

Other Applications

Other applications include use in the chemical, process, oil and gas industries due to the excellent chemical stability, corrosion and wear resistance properties. In metal forming, Sialon ceramics are used as cutting tools for machining chill cast iron and to braze and weld fixtures and pins, particularly for resistance welding.

Smooth Finish of Products

Our heater tubes, thermocouple protection tubes, riser tubes, Westofen dosing tubes, ladles, hooks, extrusion dies, cutting tools and welding pins have excellent non-wetting properties and a smooth surface.
