For to detect the mechanism of the product phase and the assignment of the two reactant on the solid state reaction of TiO₂ with the CaSO₄ and CaCO₃ respectively at the reaction temperature 900℃ - 1400℃, the refractive microscope, scanning electron microscope, and electron dispersive spectroscope analysis were examined.
For the reaction of TiO₂ with CaSO₄ the product phase which earned is CaTiO₃perovskite and from the first, the intermediate product of TiO₂· CaO·SO₂ was formed.
However, the main product phase is Ca₃Ti₂O7, which is coexisted in the product layer, at the reaction of TiO₂ with CaCO₃·TiO₂ was diffused into CaSO₄ and CaCO₃ reactant side is both two reaction. Specially, in the case of CaCO₃, the transfer of TiO₂ is rapid through the pore, which was formed with vaporization of CO₂ gas.
