In modern technical terminology the term sintering is used to describe the phenomena which occur when useful solid products are made from inorganic powders—either metallic or nonmetallic. The process is relatively easily accomplished. An array of particles of suitable size (commonly a few microns or less in diameter) is heated to a temperature between 1/2 and 3/4 of the absolute melting point for times of the order of 1 hr. During this treatment the particles join together, the piece shrinks, and much of the void volume which resulted from the initial misfit of the powder particles is eliminated.
