Formation of colloidal assemblies in suspensions for Pb(Mg1/3Nb2/3)O3 synthesis: Monte Carlo simulation study

“…5 The method enables the production of dense ceramics sintered at only 950 C, which is about 200 K lower in comparison to conventional methods, with dielectric properties comparable to the values from the literature. 6,7 In our method PMN is synthesized in a one step solid-state reaction. We believe this is achieved by manipulating the spatial distribution of the reagent particles in the powder mixture.…”

Growth and Characterization of Pb(Mg_1/3Nb_2/3)O₃ Crystals by a Single-Step Low-Temperature Process

“…It is consisted of two link calcinations steps [5]. Numerous researches to avoid two calcination steps have been reported on the preparation of single-phase perovskite PMN or PMN-PT crystals via developing intimate reaction among constituents, such as molten salt synthesis [6], mechanochemical process [7], and modified mixed oxide methods [8]. Although these approaches have enriched the means of preparing PMN and PMN-PT crystals, all of these methods bear some demerits: mechanochemical process is neither cost-effective nor suitable for industrial production; and wet processes require expensive and fine starting materials and complex process.…”

Pb((Mg0.7Zn0.3)1/3Nb2/3)O3 Relaxor Ferroelectric Ceramics by a Reaction-Sintering Process

“…The second calcination and pulverization stages in the columbite route were bypassed in the simplified columbite route. In the study of Han and Kim, PMN powder with >99% perovskite phase was prepared by adding an aqueous Mg(NO 3 ) 2 solution rather than MgO to the alcoholic slurry of PbO * E-mail: ycliou@mail.ksut.edu.tw and Nb 2 O 5 , followed by calcination at 950 • C for 2 h [8]. Liou et al proposed a reaction-sintering process to prepare PMN and Pb(Fe 1/2 Nb 1/2 )O 3 (PFN) ceramics [9,10].…”
