Abstract
The crystalline phase of Mg3BPO7 was obtained by gel combustion method and solid-phase synthesis with optimization of annealing temperatures. The effect of precursors and synthesis conditions on the formation of Mg3BPO7 was analyzed by X-ray powder diffraction and IR spectroscopy. It was shown that the formation of a mixture of kotoite Mg3B2O6 and farringtonite Mg3P2O8 prevents the formation of Mg3BPO7, whereas a significant excess of periclase MgO promotes the production of Mg3BPO7.
期刊介绍:
Doklady Chemistry is a journal that publishes new research in chemistry and chemical engineering of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
