摘要

通过优化退火温度，采用凝胶燃烧法和固相合成法制备了Mg3BPO7的结晶相。采用x射线粉末衍射和红外光谱分析了前驱体和合成条件对Mg3BPO7形成的影响。结果表明，钾长石Mg3B2O6和钾长石Mg3P2O8的混合物的形成阻止了Mg3BPO7的形成，而镁长石MgO的过量则促进了Mg3BPO7的生成。

Features of the Synthesis and Crystallization of Mg3BPO7

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.
