摘要:

AbstractThe thermal behaviour of two previously described cobalt telluromolybdates: Co4TeMo3O16and CoTeMoO6was investigated and the thermal decomposition products of these compounds were determined. Two new compounds: the cobalt orthotellurate Co3TeO6and the cobalt telluromolybdate Co3Te2MoO10were synthesized and their X‐ray and thermal characterization give

摘要:

AbstractThe simple and double salts of hexamolybdotelluric(VI) acid, M3[TeMo6O24] · nH2O(NH4)2xM3−x[TeMo6O24] · mH2O, as well as substitutive telluromolybdates MTe y6+Mo1−yO4and additive telluromolybdates MTe4+MoO6, where M = Ni, Mn, Zn, Cu have been prepared. The products of the thermal decomposition of the simple salts of hexamolybdotelluric(VI) acid are the respective substitutive telluromolybdates. MoO3, and occasionally molybdates. MMoO4.The double salts decomposition involves the total reduction of Te6+to Te4+and the formation of respective molybdates or additive telluromolybdates and MoO3.The obtained preparations have been characterized by the chemical and X‐ray methods. The substitutive telluromolybdates adopt a wolframitetype structure as the high‐pressure modifications of Co, Ni, Mn, and Zn molybdates reported by Young
