Synthesis and Characterization of Lead Free Calcium Bismuth Titanate (Ca0.25Bi0.5 TiO3) Piezoelectric Ceramics

Bismuth layer-structured piezoelectric (BLSP) calcium bismuth titanate (Ca0.25Bi0.5TiO3) piezoelectric ceramics have been prepared via a conventional sol gel reaction method by mixing the desired chemicals in stoichiometric amounts. Calcium bismuth titanate (CBT) samples were characterized by means of XRD, SEM and FTIR spectroscopy. X-ray diffraction (XRD) analysis revealed that CBT ceramics exhibit a single phase orthorhombic structure. The SEM images confirm its morphological size ranging from 1.00 to 2.75 µm. FTIR analysis reveals that calcium bismuth titanate has been prepared successfully, and the ratio of calcium, bismuth and titania was found to be 0.25:0.50:1.00, respectively. The photocatalytic removal of Methylene Blue, cadmium (Cd2+) and other toxic heavy metals will be carried out using CBT materials.

Copper Salicylate

This paper describes the synthesis and characterization of a copper-based ballistic modifier, copper subsalicylate (monobasic copper salicylate), and its performance in green-type propellants. New lead-free ballistic modifiers and phthalatefree plasticizers with reduced toxicity, less harmful to the environment, have been employed to replace their traditional additives in green-type double-base propellant preparations. The characterization of the chemical compound was performed by FTIR, TGA-DSC, and WAXS, indicating that copper subsalicylate was obtained. The results of the characterization of propellant compositions showed that copper subsalicylate, in combination with a bismuth salt, could be a substitute for the traditional lead-based ballistic modifier producing green-type propellants without reducing ballistic performance.
