カルシウムの腐食反応を活用したCaTiO<SUB>3</SUB>の合成

Abstract

Attempts have been made to obtain CaTiO3 powder by mixture of corrosion products of calcium in H2O2 solution at 373 K and titanium in H2O2+NH3 solution at room temperature for a few hours. The white calcium hydroxide and yellow peroxotitanium hydroxide aboves were mixtured and sintered at 673-1273 K for 7.2 ks. CaTiO3 particles in micron sizes have been identified by XRD analysis and SEM observations. As an example of the corrosion synthesis method, the synthesis of CaTiO3 was electrochemically considered as the mixture of corrosion products of calcium and titanium in corrosive environments.
