Synthesis of Yttrium–Aluminum Garnet Using a Microreactor with Impinging Jets

Abstract—Yttrium-aluminum garnet (YAG) nanoparticles are synthesized by the coprecipitation of yttrium and aluminum hydroxides in a microreactor with freely impinging jets, followed by the thermal treatment of the coprecipitation products. According to the results of X-ray phase analysis, the coprecipitated hydroxides are X-ray amorphous. Analysis of the product of the thermal treatment of hydroxides at 1000°C for 10 min indicates the formation of Y₃Al₅O₁₂ crystals. The method developed by us makes it possible to carry out the synthesis quickly, ensures low energy consumption, does not require laborious operations, and is technologically advanced and easily scalable.
