The sintering of magnesium oxide compacts with seventeen kinds of magnesium phosphate additions (1≤MgO/P2O5 ratios of the additives≤3) in the concentrations of 1.0mol% and 3.0mol% was investigated. The phase-change processes and the densification processes were studied from room temperature up to 1400°C. Relative densities and porosities of these compacts, heated at 1400°C for 5h, were measured to evaluate their sinterabilities. The sintering of MgO compact was accelerated by the addition of Mg2P2O7(MgO/P2O5=2); such promotion of the densification may be accomplished by the enough active mass transfer through the solid state to form Mg3(PO4)2 and an amorphous phase and then by an increase in liquid phases formed above 1100°C in Mg(PO3)2-Mg2P2O7 system, in Mg2P2O7-Mg3(PO4)2 system, and in MgO-Mg3(PO4)2 system. MgO compacts, sintered by the addition of magnesium phosphates, showed higher values of relative densities than that of the pure MgO compact; this may be chiefly due to the reduction of open porosity.
