Abstract
The technique of hot pressing and the factors to be considered in designing suitable equipment are discussed. Examples are quoted of three main classes of materials: (a) unbonded hard materials, (b) materials containing a small amount of a cementing phase or impurity affecting densification, and (c) materials containing an appreciable amount of a cementing phase. Current theories concerning the mechanism of densification during hot pressing are discussed.
