  • ScienceBased Understanding of Ceramic Powder

    Sciencebased Understanding Of Ceramic Powder

    Sep 01, 2006 Ceramic powders are commonly pressed in steel dies or rubber bags with the aim of producing a near-net-shape green body for subsequent sintering. Density gradients in these compacts, introduced during the pressing operation, are often severe enough to cause distortions in the shape of the part during sintering due to nonuniform shrinkage.

    Grinding or even milling may seem an obvious requirement if you want to achieve a fine powder. For some materials, e.g. many ceramic powders, grinding presents no problems and should always be performed. However, for some materials grinding can be a serious problem leading in some cases to poor powder diffraction data.
