Equilibrios al estado sólido entre frases de solución sólida en sistemas minerales binarios: Sistema RbBr-RbI

M.M. REVENTÓS, N. B. CHANH, J. M. AMIGO

Abstract


X-ray diffraction has been used to study the de equilimixtion in solid state of Rb(BrXIi..) solid solutions The compositions of the phases in equilibrium at room temnerature are 0.18 RbBr-0.82 RbI and 0.96 RbBr-0.04 ÉZb1, respectively. The maximum critical  temperature of the demixtion is 422ºC, corresponding to the composition X~t.1= 0.35. AS a result of this experimental work the existente of a  single-phase region at high-temperature and a two-phases region at interdifracmediate and  low-temperature has been established.
