【 摘 要 】

The paper presents the results of a study of the simultaneously receive β-wollastonite in autoclave beskrainiye leucoxene ore Yarega field. The parameters of thermal treatment of calcium metasilicate hydrate with the production of β-wollastonite were determined by thermogravimetric and x-ray phase analyses. With the help of electron microscopy it was found that the resulting CaSiO3 has a needle shape. The possibility of using the obtained wollastonite in the production of ceramic composites was studied and the compositions of ceramic masses and the modes of its heat treatment were determined.
