It is shown that the method of precursor synthesis by spraying hot solutions highly concentrated in zirconium into concentrated ammonia solutions, in combination with mechanical treatment in optimal modes, provides PSZD nanopowders, from which ceramics with high mechanical strength (800 MPa) can be made even with this method of powder consolidation. like semi-dry pressing. The effect of the temperature of synthesis of hydroxides on the characteristics of powders and ceramics has been studied. Tab. 2, ill. 6, bibliography: 10 titles.
