Abstract
A BSTRACT The influence of the coprecipitation of bismuth and iron hydroxides in microreactors of various types on the formation of nanocrystalline bismuth orthoferrite during the heat treatment of the deposit was described. Free impinging-jets microreactor, microreactor with submerged jets, microreactor with intensively swirling flows were used. It was revealed that nanocrystalline bismuth orthoferrite with the smallest weighted average crystallite size of 12 nm is formed when a microreactor with tangentially swirling flows of reagent solutions is used for coprecipitation of hydroxides. The minimum size of BiFeO 3 crystallites according to transmission electron microscopy data is determined as 3–4 nm.
