SINTERING

Sintering is a manufacturing process for solid materials by heating powders to temperatures below their melting point, allowing partial fusion of the particles together without completely melting them. This process, used mainly in the ceramics and metallurgical industry (e.g., tungsten carbide), aims to densify a material, give it enhanced mechanical properties, and make it more resistant.

Sintering generally begins with the preparation of fine powders, which can be in Metal, in Ceramics or in polymer. These powders are then compacted into a mold. This mixture is heated to a specific Temperature, generally lower than the melting Temperature of the base Material, but high enough to cause partial fusion of the particles. This phenomenon creates contact points between the grains, thus forming a solid structure. Depending on Temperature, pressure and Time conditions, various Materials can be obtained with great dimensional precision and optimal homogeneity.
