For the first time the differentiation of guadruple mutual system Li,Na,Са//F,WO4 was made. Derive phases are constructed and stable complexes of system are revealed. There were developed the reactions of chemical interaction which are typical for the lines of complete conversion for the mentioned quadruple mutual system and confirmed by x-ray phase analysis. Quadruple system LiF-Li2WO4-Na2WO4-CaWO4 was investigated using differential-thermal analysis with applying projection-thermographic method. This system is a stable tetrahedron of quadruple mutual system Li,Na,Са//F,WO4. There was built and experimentally verified the topological model of the systems state diagram revealed two invariant points.
