Аннотация: We have studied the influence of the sintering temperature and time and the composition and amount of the metastable binder δ*-Bi2O3 on the strength properties of ceramics prepared from cast MgO and demonstrated the feasibility of producing dense ceramics with a hardness of up to 67–68 HRC using the metastable phase δ*-Bi2O3, withoПоказать полностьюut mechanical load. A unique feature of the materials studied here is the possibility of bonding starting ceramic particles on account of the high chemical activity of metastable phases and products of their decomposition “at the instant of conversion” as a result of the local increase in temperature due to the exothermic decomposition of the metastable states.
