Look at the phase diagrams for your ceramic systems of interest. Then select
low melting binaries and coat the grains of ceramic with an appropriate
specie. Analogously, one can sinter nickel powders at a low temperature by
first coating them with phosphorous, which offers the further advantage of
being fugitive later under select conditions.
