Phase formation in ceramic masses containing metadiabases

The processes of mullitization of high-temperature ceramic masses containing metadiabases have been studied. A quantitative relationship has been shown between mullite, quartz and plagioclase. It has been established that at firing temperatures of 1180 - 1200 ° C, the introduction of up to 30% by weight of metadiabases accelerates the process of mullitization, contributes to the formation of a more perfect structure of the emitted mullite. In ceramic masses, mullite crystallizes mainly from a kaolinite residue, as well as from plagioclase grains. Tab. 1, ill. 3, bibliography: 10 titles.
