Abstract

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.
