ternary phasediagram is calculated. A regular solution is assumed for binary solubility and the derived interaction parameters are used to calculate the deviation from ideality of the ternary system using a quasi-regular solution model. Comparison is made between theoretical and experimental results on liquid epitaxial layers. It is suggested that a solid/solid miscibility gap in the Ga/In/P system is

trivalent organophosphorus acids containing PH and POSiMe3 fragments with various derivatives of formamide is proposed as convenient methods for the synthesis of new N-substituted aminomethylenebisorganophosphorusacids and their derivatives with three-, four-, and five-coordinated phosphorus. Also the new functionalized derivatives of the new aminomethylenebisphosphinic acids with substituted hydroxymethyl
