Structure and properties of highly refractory ceramics based on cerium dioxide and its solid solutions
Ceramics based on solid solutions of cerium dioxide and tantalum pentoxide possess a greater sintering activity than CeO2 without additives.
The increase in the Ta2O5 concentration increases the degree of recrystallization, as a result of which there is a reduction in the strength of the ceramic and also an increase in the predominant radius of the pores.
The use of electrofused grains as a filler and fractions −0.06 mm as the bond retards the sintering process and leads to an increase in the thermal shocking resistance of the ceramic specimens.
