Single crystals of new bromosilicate compound Ca 3 SiO 4 Br 2 were grown out of high-temperature Ca 2 SiO 4 / CaBr 2 melts by the slow cooling process. Colorless, transparent and flaky crystals of Ca 3 SiO 4 Br 2 were directly isolated from the final solid coagulation. The as-obtained crystals were
