Abstract
Bulk (crystal-chemical, structural) and surface (chemical composition of the surface, acid-base) properties of solid solutions of the InSb-CdS, CdTe-CdS systems (compared to the initial binary compounds InSb, CdTe, CdS), prepared in the form of fine powders and thin films have been studied in an integrated manner involving up-to-date techniques. Solid solutions are certified as substitution solid solutions with a wurtzite structure.The consistent patterns have been revealed in the studied properties changes with changes in the systems compositions that have both smooth (subject to Vegard’s law) and extreme nature. The predominant influence on them by the first binary components (InSb, CdTe) has been demonstrated and justified.The acidic sites’ nature, strength, concentration have been determined. An increased sensitivity of the system components surfaces (at pHiso<7) to the main gases has been found. The most active of them have been recommended as primary sensors materials for measuring cells for ammonia micro impurities.
