Piezoelectric properties of (K0.5Na0.5)NbO3

Jul 01, 2016(K,Na)NbO 3 (KNN)-based lead-free piezoceramics have been the spotlight in search for practically viable candidates to replace the hazardous but dominating lead-containing counterparts. In this work, BaTiO 3 (BT) modified KNN ceramics were fabricated by spark plasma sintering (SPS) and the influence of BT content as well as sintering temperature on the phase structure, microstructure, and

Sol–gel process

The Stber process is a well-studied example of polymerization of an alkoxide, specifically TEOS.The chemical formula for TEOS is given by Si(OC 2 H 5) 4, or Si(OR) 4, where the alkyl group R = C 2 H 5. Alkoxides are ideal chemical precursors for sol–gel synthesis because they react readily with water. The reaction is called hydrolysis, because a hydroxyl ion becomes attached to the silicon

Multiferroic properties of BiFeO3–BaTiO3 based ceramics

products were crushed and ground using a planetary ball mill for 2h with a zirconia vessel and balls. The ground powder was then granulated with an aqueous polyvinyl alcohol solution as a binder. The granulated powder was pressed into 13mm diameter and 1mm thick disks. Prior to sintering, the binder was decom-posed at 500C for 1h in air.
