Phase diagram studies for the growth of (Mg,Zr):SrGa${}_{12}$O${}_{19}$ crystals

Abstract

By differential thermal analysis a concentration field suitable for the growth of Zr, Mg codoped strontium hexagallate crystals was observed that corresponds well with experimental results from Mateika and Laurien, J. Crystal Growth 52 (1981) 566-572. It was shown that the melting point of doped crystal is ca. 60 K higher than that of undoped crystals. This higher melting points indicates hexagallate phase stabilization by Zr, Mg codoping, and increases the growth window, compared to undoped SrO-Ga${}_2$O${}_3$ melts.
