System SrGa2S4-LaGaS3
Aliev,Shirinov
, p. 757 - 758 (2000)
Phase relations in the SrGa2S4-LaGaS3 system were studied by physicochemical analysis, and the SrGa2S4-LaGaS3 phase diagram was mapped out. The system was found to contain the quaternary compound SrLaGa3S7, which melts congruently at 1290 K and has a tetragonal structure. The composition ranges of the SrGa2S4- and SrLaGa3S7-based soliid solutions were determined.
Synthesis and luminescent properties of Eu-activated CaGa2S 4 and SrGa2S4

SrS, CaS, SrGa2S4:Eu, and CaGa2S 4:Eu were prepared, and the luminescent properties of the latter two compounds were studied. It is shown that sufficiently pure SrS and CaS powders can be prepared via long-term

Phase equilibria in the SrS-Ga2S3 system

In the SrS-Ga2S3 system, there exist two individual compounds: SrGa2S4 (a = 2.084 nm, b = 2.050 nm, c = 1.220 nm; congruent melting at 1530 K) and Sr2Ga2S5 (a = 1.253 nm, b = 1.203 nm, c = 1.117 nm; peri- tectic melting at 1330 K); both are orthorhombic. We discovered a compound of composition Sr4Ga 2S7; this compound crystallizes in cubic system with the unit cell parameter a = 0.6008 nm, space group Pa3, and decomposes by a solid-phase reaction at 870 K. Eutectic compositions are 42 and 73 mol % Ga 2S3; eutectic melting temperatures are 1210 and 1170 K, respectively. The SrS solubility in ?-Ga2S3 at 1070 K reaches 4 mol %.
