Ba2Bi2[Zn(PO4)4]: Ionic-Isolation-Activated First Barium Bismuth Zincophosphate with Unprecedented ∞[Zn(PO4)4]10- Chains and Balanced Overall Performance

Exploration of ultraviolet phosphates with balanced overall performance is of great significance and difficulty. Herein, the first barium bismuth zincophosphate, Ba2Bi2[Zn(PO4)4], was rationally obtained by ion-mixing and anionic condensation, while...

Phase Development of Barium Bismuth Titanate by Modified Solid State Route

Barium bismuth titanate materials are noted for ferroelectric behavior, competitor to lead based relaxor dielectrics and even for coating having wear resistance, toughness for improving surface engineering applications. In the present context, a modified solid state process aided by agate-mortar activation for milling is carried in compare to mechanochemical milling, melt-quench method to generate the complex ceramic structure. Molar ratio of BaO:Bi2O3:TiO2 1:2:4 ratio have been taken with fixed soaking temperature to develop the material. Activation milling period is varied for 20 hours, 25 hours and 30 hours while soaking period descends in the order 10 hours, 8 hours and 6 hours keeping fixed temperature of about 700°C. XRD confirms the presence of peaks for all cases. Crystallite size is estimated by Scherrers formula with proper planes of index corresponding to JCPDS data. FTIR confirmed the phases developed by XRD while indicating the proper M-O bond formation from analysis in the required spectral range. EDX spectra analysis given the presence of required elements present in the sample.
