EFFECT OF SILICON DIPHOSPHATE ADDITION ON SINTERING OF MAGNESIUM OXIDE.

Abstract

The sintering of MgO with SiP//2O//7 in the concentrations of 0. 1, 0. 5, 1. 0 and 3. 0 mol% has been studied at increasing temperatures up to 1400 degree C. The microstructure of resultant specimens was examined. The results of sintering at increasing temperatures were nearly in accord with those at constant temperature. At increasing temperatures, the shrinkage curves of MgO specimens with SiP//2O//7 were similar to that of the pure MgO specimen.
