摘要：
Friedman and Flynn-Wall-Ozava methods were used to study the nonisothermal decomposition kinetics of the Zn4CO3(OH)(6)/Al(OH)(3) system. It was shown that thermolysis processes occur in the kinetic mode and, after a degree of decomposition exceeding 0.9 is reached, pass under diffusion control. It was found that, upon co-grinding of the components, the apparent activation energy increases as compared with the values for the starting mixture.
