摘要：
The thermal decomposition processes of（MgCO;）;·Mg（OH）;·5H;O（MCH）,5ZnO·2CO;·4H;O（ZCH）,NiCO;·2Ni（OH）;·4H;O（NCH）,PbCO;（LC）and [Cr（OH）;];·CO;·8H;O（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.
