摘要
A method was developed for differentiating multicomponent systems with incongruent compounds. This method was employed to differentiate the Li,Na,Srparallel toF,WO4 quaternary reciprocal system. Unit phase assernblages were recognized, and the phase tree was constructed. Chemical reactions characteristic of conversion elements were derived and confirmed by X-ray powder diffraction. Differential thermal analysis combined with projective thermogravimetry was used to study the LiF-Li2WO4-Na2WO4-SrWO4 four-component system, which is the stable tetrahedron of the Li,Na,Srparallel toFWO(4) system. Two invariant points were found: one peritectic point and one tapering-out point.
