摘要:The Phase Diagrams Of The Systems Abr/smbr3 Were Reinvestigated. The Findings Of Blachnik For The Systems With A = Cs,Rb,K Were Confirmed; However,The Dimorphic Compound K3Smbr6 Is Stable Only Above 572 K. The Equilibrium Temperature,Found By E.M.F.-Measurements In A Solid State Galvanic Cell For The Reaction Rbr+k2Smbr5 = L-K3Smbr6,Is Smaller (522 K). The Formation Temperature For Rb3Smbr6 Is 279 K (Dta) And 256 K (E.M.F.) Reap. By Solution Calorimetry Was Proved That The Compounds Cs2Smbr5 And Ksm2Br7 Don'T Exist At 0 K. In The System Nabr/smbr3 Only One Hitherto Unknown Dimorphic Compound Na3Smbr3 Exists Above 473 K. L-Na3Smbr Crystallizes In The Hexagonal Space Group,Above 519 K H-Na3Smbr6 Has The Monoclinic Cryolite-Structure. Powder Patterns Of Other Compounds Not Yet Investigated-H/l-A(3)Smbr(6),Asm(2)Br(7) (A = Cs,Rb,K) And Cs2Smbr5-Were Indexed Analogously To Known Structure Families. The Structure Parameters Of Smbr3 . 6H(2)O Were Determined By Single-Crystal Measurements.
