%X Solid state reaction between CaCO3 and MoO3 was studied using non-isothermal thermal analysis method. On the basis of TG curve and extent of reaction, the chosen 13 solid reaction mechanism functions were fitted respectively. The Coats-Redfern method used for model fitting and kinetic parameter was calculated by slope and intercept. The results indicate that the reaction between CaCO3 and MoO3 begins at 450℃, its reaction mechanism belongs to random nucleation and growth with integral form g(α)=-ln(1-α), the apparent activation energy is determined to be about 170.2 kJ/mol with pre-exponential factor of about 1.3×107 s-1.
