The goal is to develop and demonstrate high density stainless steel pellets or pucks containing surrogate materials for plutonium oxide embedded within the metal matrix. Using liquid phase sintering, it is possible to create metal forms without melting the base materials or using high pressures. Liquid phase sintering fuses a base material using a small amount of low melting alloy powder mixed into a base alloy powder; it can produce stable forms at temperatures which are significantly lower than the melting point of the base alloy, and in times significantly shorter than required for traditional sintering.
