METHOD OF PRODUCING LEAD MAGNOTANTALATE POWDER WITH PEROVSKITE STRUCTURE

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to production of oxide powder with composition Pb(Mg1/3Ta2/3O3) having a perovskite structure and can be used in producing materials for piezoelectric engineering. The method involves mixing a tantalum compound with aqueous solutions of lead and magnesium salts in stoichiometric ratio which yields a composition of lead magnotantalate with a perovskite structure - Pb(Mg1/3Ta2/3O3), and then thermal treatment of the obtained suspension. The tantalum compound used is tantalum hydroxide and the solutions of magnesium and lead salts are solutions of magnesium and lead acetates which are added successively, the product being thermally treated at 800-850C. ^ EFFECT: low synthesis temperature, high output and purity of the end product. ^ 1 tbl, 1 ex
