... of the constituents: the smaller the grains, the faster they dissolve. In refractories, however, the smallest grains, by design, bond with the coarser grains (the aggregate), and since this bonding occurs by liquid-solid sintering, the matrix materials (the bonding phases) have the lowest melting temperatures...
