Synthesis of natural vanadates shows that most of them are stable in an acid environment. Phase studies of a portion of the system CaO-V2O5-H2O indicate that calcium vanadates are an indicator of environmental pH conditions. Some minerals, such as pascoute, indicate rapid evaporation of vanadite solutions; other minerals, such as hewettite, show that slow evaporation took place. Cursory examination of systems K2O-UO2-(NO3)2-V2O5 and CaO-UO2(NO3)2-V2O5, both in aqueous solution, has yielded information on the relationships among carnotite, tyuyamunite, and rauvite.
