The process of diffusional evolution (shrinkage orgrowth) of gas-filled pores in a hot-pressed ceramic is analyzed,assuming that the gas is soluble in the matrix. It is additionallyassumed that the strength of vacancy sources and sinks is finite.An equation is derived for the porosity of the ceramic at a latestage of sintering.
