摘要：
It is shown that the method of synthesis of precursors by spraying hot highly concentrated with respect to zirconium solutions into concentrated solutions of ammonia permits obtaining in combination with mechanical working under optimal conditions nanopowders of partially stabilized zirconium dioxide (PSZD), from which a ceramic with high mechanical strength (800 MPa) can be obtained even by consolidating powder by semidry pressing. The effect of the synthesis temperature of hydroxides on the characteristics of the powders and ceramic is studied.
