Tungsten Carbide Nozzle Sintering Technology

Sintering is a kind of processing that makes fine powder particles are bonded through heating process, namely turns the powdered materials into compact. This is a traditional process, which people take advantage of sintering for powder metallurgy, ceramics, fireproofing and heat resistance materials, etc. In general, after powder molding, the compact by sintering is a polycrystalline material, which is composed of crystal, vitreous and pore. The sintering process directly affects the microstructure of the grain size, pore size and the shape and distribution of grain boundaries, which is related with material properties.

In addition, problems due to the sintering will be difficult to make up by following procedure so that the choice of the sintering process has also been an aspect of the practical production for considering. At present, the common sintering methods are vacuum sintering, microwave sintering, and hot isostatic pressing (HIP) combined with microwave sintering, etc.
