Structure formation processes upon sol-gel method of yttrium-silicate material production

Materials based on yttrium silicates have been synthesized by the sol-gel method. The influence of the amount of yttrium oxide, which varied from 10 to 50% (molar content), and the molar ratio of water: alcoholate were investigated. The processes of structure formation, the nature of the crystallization of gels during heat treatment in the temperature range 650 - 1300 ° C have been studied. Il. 5, bibliography: 8 titles.
