Abstract

Nanosized yttrium–aluminum garnet (YAG) powders are synthesized in a microreactor with swirling flows by the coprecipitation of yttrium and aluminum hydroxides followed by heat treatment. The resulting mixture of hydroxides is X-ray amorphous according to X-ray phase analysis. Thermal treatment of hydroxides at 1100°C for 1 h leads to the formation of Y3Al5O12 nanocrystals. The method we developed is technologically advanced, easily scalable, saves energy and time, and does not require labor-intensive operati-ons.

在带漩涡流的微反应器中合成钇铝石榴石前驱体
摘要 纳米钇铝石榴石(YAG)粉末是通过钇和铝的氢氧化物共沉淀,然后进行热处理,在漩涡流的微反应器中合成的。根据 X 射线相分析,所得氢氧化物混合物为 X 射线非晶体。在 1100°C 下对氢氧化物进行 1 小时的热处理,可形成 Y3Al5O12 纳米晶体。我们开发的方法技术先进,易于扩展,节省能源和时间,并且不需要劳动密集型操作。
