Titanium Dioxide for Dielectric Ceramics
CAS Number: 13463-67-7
High-purity rutile titanium dioxide (TiO2) is the titanium source for barium titanate (BaTiO3) MLCC dielectrics, titanate-based microwave ceramics, and piezoelectric materials. The rutile phase is preferred over anatase for solid-state ceramic synthesis due to its higher density and reactivity with BaCO3 at calcination temperatures. Precise particle size control is critical for MLCC manufacturing.
