The main bifurcations upon firing of dense oxide ceramics

Processes during the firing of dense ceramics from pure oxides are considered from the standpoint of synergetics. An assumption is made about the presence of three regions of unstable states of evolution of the structure of the workpiece. To eliminate multistability with strongly differing in properties stable states (structures), in the region of possible bifurcation, it is possible to influence the subsequent evolution of the structure using external (for example, periodic fields) and internal (structures created in the workpiece at previous stages) control signals. Sometimes the desired structure can be obtained through self-organization of the system. Il. 2, bibliography: 16 titles.
