Determination of an Effective Viscosity of Powders as a Function of Temperaturened for powders of simple particle geometry and known particle size distribution. For practical applications, an effective viscosity is proposed as a better measure of densification characteristics. Illustration of the method is made by examining shrinkage characteristics of various ceramic powder compacts at constant rates of heating.

Solid-State Sinteringons. This approach has been successful in describing the sintering of compacts of spherical particles of Fe, Cu, Fe. O., Ag, and LiF. The relative importance of surface, grain boundary, and volume diffusion and vapor transport are discussed. Experimentally observed sintering behavior is discussed in terms of the theoretical model.

Realization of Fine-Grain Ceramicsf the effect of grain size on physical properties, but interpretations must also account for other influences such as grain bonding and internal strains, surface condition, and extrinsic flaws. Recently, attention has been focused on processing as the key to grain refinement. The diverse approaches

A general theorem is proven, demonstrating that the size distribution in the finer sizes is independent of many parameters that affect the larger size distribution.
