Titanium Dioxide Ceramic Densification Aid

CAS Number: 13463-67-7

High-purity titanium dioxide (TiO2, anatase or rutile) is used as a sintering and densification aid in alumina, barium titanate, and electronic ceramics. In alumina, 0.05–0.3 wt% TiO2 promotes liquid-phase sintering and enhances grain boundary diffusion, lowering the densification temperature and improving ionic conductivity. In BaTiO3 systems it acts as a stoichiometry corrector.
