Фазовый состав керамики Al[2]O[3]-ZrW[2]O[8]

Abstract

In the course of work the phase composition of the ceramic composite material Al[2]O[3] - 50 % ZrW[2]O[8] was studied. On the polished surface of the Al[2]O[3]-ZrW[2]O[8] sintered composite can be allocated three areas: dark gray matrix, white inclusions of an irregular form and spherical inclusions. The average size of spherical inclusions was equal to 15 [mu]m. The phase structure of ceramic composite was presented by trigonal modification of aluminum oxide, cubic zirconium tungstate, monoclinic modification of zirconium oxide and tungsten oxide.
