摘要：

The thermal decomposition processes of (MgCO3)4·Mg(OH)2·5H2O (MCH), 5ZnO·2CO3·4H2O (ZCH), NiCO3·2Ni(OH)2·4H2O (NCH), PbCO3 (LC) and [Cr(OH)5]2·CO3·8H2O (CC) were studied via TG-DSC. The results of research imply that MCH has the largest capacity of heat absorption and ZCH is second to MCH among the studied materials. The non-isothermal kinetic parameters of MCH and ZCH were calculated by Kissinger and Ozawa methods. Furthermore, thermal decomposition mechanisms of MCH and ZCH were investigated by Coats-Redfern method. Due to the large specific heat capacity, MCH and ZCH are promising to be used as a coolant in extinguishant formulations. © 2017 Editorial Department of Journal of Beijing Institute of Technology.
