Abstract

Abstract: Nanosize Pb₃Nb₂O₈ powder has been obtained at 90 ℃ from Nb₂O₅-PbO-KOH-H₂Osystem. The influence of starting materials and their molar ratios, pHvalue of the solution and the synthesis temperature were systematically investigated. Soluble niobate and lead acetate have been chosen for the synthesis of Pb₃Nb₂O₈. Pure phase product could be obtained when the molar ratio of Pb to Nb is close to 1, and concentration of KOHto 1—3 mol/L. PbOappears as the main phase when KOHconcentration is greater than 3mol/L.

Key words: Co-deposited synthesis, Pb₃Nb₂O₈, Nanosize powder
