| Abstract | Subsolidus phase relations in the M$_{2}$O(M$_{2}$CO$_{3}$)–MgO–V$_{2}$O$_{5}$ and M$_{2}$O(M$_{2}$CO$_{3}$)–CaO–V$_{2}$O$_{5}$ (M = Li, Na, K, Rb, Cs) systems are studied. Twenty mixed vanadates are obtained, of which Rb$_{2}$CaV$_{2}$O$_{7}$ , Cs$_{2}$CaV$_{2}$O$_{7}$ , LiMg$_{4}$(VO$_{4}$)$_{3}$ , RbCaVO$_{4}$ , and CsCaVO$_{4}$ are identified for the first time. Structural data are summarized for all of the mixed vanadates: the space group and lattice parameters are indicated for 14 compounds (for 6 compounds, such data are obtained for the first time), and I and d data are presented for 8 compounds. Partial series of Ca$_{3}$(VO$_{4}$)$_{2}$-based solid solutions with the general formula Ca$_{3 – x }$M$_{2x }$(VO$_{4}$)$_{2}$ (M = Na, K, Rb, Cs) are identified in the range 0 < x ≤ 0.14. Six phase diagrams (M$^{+}$ = Li, Rb, Cs; M$^{2+}$ = Mg, Ca) are investigated and are compared with the phase diagrams of the other ternary systems in question. The key features of the ternary phase diagrams and, hence, the reactivity of the constituent oxides are shown to vary systematically in going from Li$_{2}$O to Cs$_{2}$O and from MgO to SrO, which is interpreted in terms of the variation in the ionic radius of the alkali and alkaline-earth metals. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
