| Abstract | This paper deals with characterization and synthesis of zinc fluoroborate from zinc fluoride and boron by mechanochemical reaction. Zinc fluoroborate is widely used in high technological areas such as textile, chemical reaction, plating solution, and glass. In this study, zinc fluoroborate has been synthesized via high-energy ball milling method. The effect of reactant mol ratio (B/ $$\hbox {ZnF}_{2})$$ and ball milling period was investigated on the product yield. After completion of the reaction, the product in the reaction mixture (including excess reactant and side products) was purified by the extraction with water. The samples were characterized by FT-IR and $$\hbox {BF}_{4}^{-}$$ ion-selective electrode. SEM and EDX analyses were took place. Decomposition of sample was characterized by TG-DTA. The sample was sintered at 300– $$500\,{^{\circ }}\hbox {C}$$ to compare the data with TG-DTA. The results showed that decomposition of B–F bond started at $$300\,{^{\circ }}\hbox {C}$$ . As a result of these experiments, maximum yield was obtained at 0.8 molar ratio and 3000 min. of mechanochemical reaction duration with the use of ball milling. Eighty-three percentage pure zinc fluoroborate was produced by adding the purification step. |

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.
