Abstract


The purpose of this study is to increase efficiency and to reduce costs by changing the process parameters. The synthesis of zinc borate has been carried out with the reaction of zinc oxide and boric acid. In this study, zinc borate production was carried out in aqueous media using commercial zinc borate as seed. Experiments have been carried out in an isolated glass beaker. Temperature is controlled using a digital temperature sensor and magnetic stirrer provides constantly stirring during the reaction. The experiments were performed in the presence of seed and without seed.
The samples were filtered and dried at 105°C for 20 h. Dry, fine powdered zinc borate particles were produced under optimised conditions. The resulting high yield were formed utilizing various amounts of seed and high yield was obtained for saturated solution. The effect of varying the concentrations of seed, reaction time, the amount of water on yield have been investigated. As a result, zinc borate was analyzed with X-ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) and it was observed that the synthesis was carried out successfully
