NOVEL BETA SILICON CARBIDE POWDERS AND DERIVED HIGH PERFORMANCE CERAMICS

Objective

The overall aim is to establish an economic source of reliable high quality beta silicon carbide powders in Europe.

Lonza will develop the manufacture of powders by the carbothermic reduction of silica. Process options will include the addition of sintering aids to ensure their effective dispersion and agglomeration of the powder for forming by pressing. Cerex will transfer from the laboratory to the pilot scale a novel process in which silicon tetrachloride vapour is injected into a solution of calcium carbide in molten calcium chloride at 900 C to form finely divided silicon carbide powder. These processes will be characterized and optimized for processing into components by T & N Technology supported by CEIT. Correlations will be established between the chemical and physical characteristics of the powders, the structural features of the derived ceramics and the behaviour of components in demanding applications in the process, aerospace and eletronics industries.
