Conclusions
The main principles in the technology of cast ceramic or refractory materials of a grainy structure are considered using some pure oxides or their compounds as an example.
The general principles of the change in the rheological properties of the fine-grained suspensions as they are saturated by the grainy filler are considered.
A process has been developed for cast-filled systems in inactive molds and it is shown that under specific conditions this method is as good as the method of vibrocasting in active molds.
The semifinished product based on the grainy cast systems has adequate mechanical strength and low shrinkage when molded, dried, and sintered.
