Obtained from natural raw materials, such as silica sand, zirconia, bauxite, or synthetic products, such as metallic oxides, carbides or nitrides, ceramics form a homogeneous family of materials whose synthesis depends on a broad base of expertise in physical chemistry and very high temperature processes (between 1,300°C and 2,500°C). In fact, ceramics are generally shaped at ambient temperature, by unidirectional or isostatic cold or hot pressing, slip-casting, extrusion or injection, followed by high-temperature sintering.
By controlling the quality and the purity of the raw materials, as well as the various stages of the manufacturing cycle, Saint-Gobain optimizes the microstructures of these materials down to the submicron scale to create finished products with exceptional resistance to heat, chemical corrosion and wear, in order to meet the needs of demanding technical applications. These materials are often used in the processes as well as components in other high-technology industries.

FINE CERAMICS
The fine ceramics intended for tribological applications are generally manufactured from synthetic powders with very fine particle sizes.
FUNCTIONAL CERAMICS
The particular structure of microceramics confers upon them the optical, electrical or physical and chemical properties.

GRAINS AND POWDERS
Saint-Gobain produces a wide variety of powders and grains based on oxides, carbides and nitrides. These synthetic materials have been specially developed to meet the very specific needs of different industries where they are used as raw materials to manufacture abrasives and ceramics, among others.
