Production of transparent ceramic. synergetic approach

A systems approach to obtaining high-quality transparent ceramic is examined from the standpoint of synergetics. The optimal decrease of the degree of nonequilibrium of the system must be attained at all stages of fabrication of transparent ceramic: during preparation of the powder including its synthesis, introduction of densifying additives, and heat treatment. The formation of aggregates and local densification with strong solid-state bridges between particles, as a result of which pores enter the crystal, must be prevented during the preparation of the molding mix, molding, and removal of the binder as well as during sintering.
