Abstract


Paper start from the analysis of the barium titanate crystal structure , the use of XRD, SEM and other modern means of microscopic analysis , preparation of barium titanate and barium titanate-based temperature sintering X8R Dielectric Ceramics discuss the dielectric ceramic system doped change of effect and microscopic mechanism and system components and process conditions on the dielectric properties of the system . First of all, the barium titanate based incorporation the Nb2O5-CoCO3 the formation of core - shell structure as a basis for formulation , the system has been in this basic formula of Pb ( Ti0.55 Sn0.45 ) O3 doped Miscellaneous modified . Pb ( Ti0.55 Sn0.45 ) O3 on the stability of the high temperature zone has a significant improving effect , greatly improving the dielectric constant of the system under the high temperature conditions , at a test temperature of 150 ° C or about the introduction of a new Curie peak . Then, we discuss the impact of the process on the performance of the high dielectric barium titanate-based ceramic detailed analysis of the calcination , milling , sintering process of barium titanate-based dielectric ceramic dielectric performance impact . Compare different calcination temperature and finalize the barium titanate powder calcined at 1130 ℃ based materials . The result of Pb (Ti0.55, Sn0.45) O3 , and strictly control the process ultimately obtained performance to achieve the the X8R ??required temperature stable barium titanate-based media ceramic , the 1KHz to test performance parameters are: sintering temperature of 1100 ° C a dielectric constant ≥ 2300 loss tan delta ≤ 1.5 % -55 ° C to 150 ° C range within -15 % lt ; ? epsilon / epsilon lt ; 15 %
