Abstract
Methods for production of poreless finely crystalline oxide ceramics are considered in the context of the chemistry of defects and nonequilibrium. The paper demonstrates the necessity of reducing the degree of nonequilibrium of the sintering process by decreasing the mass transfer by introduction of additives that produce oxygen vacancies and by reducing the probability of the appearance of local compaction.
