Abstract
Novel powders or particles are formed by associating them with relatively small proportions of hydrolysable liquid material. The resulting particle/liquid mass is placed in a mold and sintered under conditions of heat and pressure that enables at least some of the hydrolysable liquid to react within the sintered mass. The sintered mass displays a controllable range of properties such as increased density, increased tensile strength, and improved natural polish finish. The hydrolysable liquid may partially hydrolyze and/or react with the powders and particles, but the liquid is not completely (not 100%) reduced to an inorganic oxide prior to introduction to the mold and performance of the sintering process.
