چکیده
Present study showed synthesis of novel type porous alkali niobate piezoelectric ceramics, and the formation domains photocatalytic activity for ceramics were investigated while comparing with dense to confirm enhancement domain orientation around pores. Porous Li0.06Na0.47K0.47NbO3 synthesized by a template method using polymethylmethacrylate as pore former agent. Uniform pores 6 µm in diameter dispersed ceramics. 10 vol % agent voltage coefficient, 29 mVm/N, which is same that Smaller striped formed at an edge on indicating was promoted electric field concentration Through photoreduction reaction Ag+ ion, local precipitation Ag shown poled whereas located over entire surface unpoled Highest photodecomposition test methylene blue. These results clearly indicated enhanced ferroelectric

Dielectric and piezoelectric properties of sodium lithium niobate Na1−xLixNbO3 lead free ferroelectric ceramics
High density sodium lithium niobate lead free ceramics near the morphtropic phase boundary [NaxLi1−xNbO3, (LNN), x=0.12] were prepared by the solid state reaction method. XRD patterns showed that the lattice structures were changed after polarization. The temperature dependence of the dielectric constant and dielectric loss, pyroelectric coefficient and DSC curves of LNN ceramics showed that th...
متن کاملSintering of Lead-Free Piezoelectric Sodium Potassium Niobate Ceramics
The potassium sodium niobate, K0.5Na0.5NbO₃, solid solution (KNN) is considered as one of the most promising, environment-friendly, lead-free candidates to replace highly efficient, lead-based piezoelectrics. Since the first reports of KNN, it has been recognized that obtaining phase-pure materials with a high density and a uniform, fine-grained microstructure is a major challenge. For this rea...
متن کاملBarium titanate as a ferroelectric and piezoelectric ceramics
Barium titanate is a member of a large family of compounds with the general formula ABO3 called perovskites, as the crystal size of barium titanate increases and at critical crystalline size crystal structure of barium titanate transformed from cubic to tetragonal. Transformation of crystal structure is also take place at Curi temperature. Cubic structure show paramagenatic behavior while tetra...
