Microwave Synthesis of CaTiO3 Nanoparticles by the Sol-Gel Method

Abstract

A technique for the microwave-activated synthesis of calcium titanate nanopowder was proposed. The microwave effect used in the synthesis of CaTiO3 samples when using sodium carbonate as a precipitant allowed obtaining a chemically homogeneous nanopowder with a significant reduction of the process time.       References1.
