HYDROTHERMAL SYNTHESIS OF R2SIO4 COMPOUNDS

Abstract

The mineral synthesis research has evolved into two different studies: first, ferrites and the effects of ultrahigh pressure treatment; second, hydrothermal synthesis of R2SiO4 (olivine-type) minerals. The second study was instigated to fill time gaps in the ferrite progress. The pressure system for the hydrothermal synthesis equipment was completed and the synthesis of olivine group minerals was begun immediately. The olivines are neosilicates with an ideal chemical formula of R2SiO4, where R can be Mg+2, Fe+2, Mn+2, Ca+2, and other divalent metals. The olivine structure consists of individual SiO4 tetrahedra bound together by the divalent cations.
