According to the developed methodology, based on the isothermal diffusion of the initial binary compounds (InP, ZnS), their physical and physicochemical properties, solid solutions of different composition ((InP)x (ZnS)1-x) have been obtained. X-ray examinations have been conducted which allows to certify them as substitution solid solution with sphalerite structure and acid-base properties studies (pH isoelectric state — pHISO). The consistent patterns of changes in the composition of the studied (bulk and surface) properties, which are of predominantly smooth nature, have been established. A correlation between theoretical calculated crystal density and acid sites strength (pHISO) has been found which served as the basis for recommending a less labour-consuming way to search for the advanced materials for semiconductor gas analyzers.
