Effect of Calcination Kinetics and Microwave Sintering Parameters on Dielectric and Peizo-Electric Properties of(K0.5Na0.5) NBO3 Ceramics
An efficient solid-state approach was established to synthesize (K0.5Na0.5) NbO3 ceramics using calcination kinetics and microwave assisted sintering. Milling of carbonate and oxide raw materials were carried out for 15h to obtain homogeneous nano particles. The crystallite size of 5.30 nm was obtained for the KNN system after calcination through optimized parameters and observed to be stoichio...
متن کاملEnhanced dielectric and piezoelectric properties of xBaZrO3-(12x)BaTiO3 ceramics
xBaZrO3-(1!x)BaTiO3 solid solutions (x 1⁄4 0, 0.04, 0.06, 0.08, 0.12, and 0.18) synthesized via conventional solid state reaction method exhibit piezoelectric coefficients comparable to those of “hard” PZT-8, PZT-4, and even “soft” PZT-5A. Doping also improves the poling efficiency of xBaZrO3-(1!x)BaTiO3 ceramics. Study of temperature dependence of the dielectric and piezoelectric properties re...
متن کاملLOW-TEMPERATURE SINTERING AND MICROWAVE DIELECTRIC PROPERTIES OF (Zn0.65Mg0.35)TiO3-CaTiO3 CERAMICS WITH H3BO3 ADDITION
Low-melting H3BO3, acting as sintering aid, was used to reduce the sintering temperature of 5 wt.% CaTiO3-doped (Zn0.65Mg0.35)TiO3 ceramics. The sintering behaviors, microstructures and microwave dielectric properties with different amounts of H3BO3 addition were investigated. The results showed that H3BO3 additive was very effective for lowering the sintering temperature and improving the bulk...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولMicrowave Sintering of Thermistor Ceramics
Microwave sintering is a new sintering technology developed in the middle to late period of the 1980’s, which is characterized by fast densification for ceramic materials[1]. In recent years, microwave heating has been well employed in the field of sintering and joining of ceramics as a result of its advantages against conventional methods. These ceramic materials include oxides, mixed oxides, ...
