Barium titanate (BTO) hollow particles were prepared using two-step chemical solution deposition with a template particle. Polystyrene (PSt) was selected as the template particle, and N-(hydroxymethyl)acrylamide (HMAm) was polymerized as a comonomer to generate the hydrophilic group on the PSt template particle surface. The BTO monophase was attained at [Ba]/[TiO2] = 1.0 using 350°C pre-annealed TiO2 precursor hollow particles. The obtained BTO particle was a hollow structure with shell thickness of approximately 45 nm. The surface area of the obtained BTO hollow particle was 12 m2/g, which was approximately twice as large as that of alkoxide-derived BTO particles created with the same annealing temperature.
