NOVELTY - Preparation of flaky calcium borate/graphene oxide composite particles involves preparing borax solution and calcium nitrate solution by ultrasonically dispersion, adding borax solution into graphite oxide solution, adding calcium nitrate solution to mixture of borax and graphite oxide, stirring, adding obtained mixture into a reactor, heating for predetermined time, cooling reaction mixture, filtering, and washing obtained particles. USE - Preparation of flaky calcium borate/graphene oxide composite particles (claimed). ADVANTAGE - The method enables preparation of calcium borate/graphene oxide composite particles by environmentally-friendly process.
