Abstract
Porous tetragonal BaTiO3 ceramic was successfully prepared by a combination of hydrothermal and low-temperature-sintering method. The hollow TiO2@BaCO3 as the sintering precursor was synthesized via a simple hydrothermal method, and then porous BaTiO3 was generated by calcining the hollow TiO2@BaCO3 precursor at 900 °C without additive. The hollow TiO2@BaCO3 structure plays two important roles in the preparing of the porous BaTiO3 ceramic. First, the TiO2@BaCO3 hollow structure provides high surface areas and increases the contact points between BaCO3 and TiO2, which can reduce the sintering temperature of the BaTiO3 ceramic. Second, the cavity of the ordered arranged TiO2@BaCO3 hollow sphere shows important influence on the porous structure, and the pore size of the as-prepared porous BaTiO3 ceramic can be tuned from several nanometers to hundreds nanomters by changing the sintering temperature. The formation mechanism of the porous BaTiO3 ceramic was proposed.
