Abstract

Ceramics are non-metallic inorganic materials and vary in composition. They are made by mixing the fine powders of the ingredient material with water and adhesive binder. This is then squeezed into a mould to obtain the desired shape, air dried to dry, and the binder is then burned out by thermal treatment. Firing or sintering at this stage at a high temperature (over 1000 degrees Celsius) makes the residual material extremely dense. Modern ceramics do not use either water or binding agents to bind or compress the ceramic shapes, and use an Isostatic Pressing Technology, to fuse the ceramic granules under very high pressure to form a non hygroscopic and non water dependant unit, of such high strength, that after high temperature fusion, the resultant component can even be machined on a conventional Cnc machine like metals. The final microscopic structure of the resultant ceramic is greatly dependent on the thermal process used, the highest temperature reached, and the duration of furnace heat treatment.
