15 صفحه اولEffect 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 کاملthe effects of previewing and providing background knowledge on iranian university efl learners’ comprehension of literary and academic texts
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
