Heat capacity of calcium carbonate

[MariusChE]

Hi everyone

Could you please help me? I need the heat capacity of CaCO3 in a band between 20°C and 150°C (65°F and 300°F). And, by the way, Google search = 16,200 results; I've probably looked at over 300 without success.

Thank you in advance
Marius

In case you want Cp as a function of temperature....
Cp(CaCO3)=a+bT+c(T)^-2 [J/mol.C)
where T=temperature [K]
and for CaCO3...
a=82.34
b=4.975E-2
c=-12.87E+5
This expression is apparently good between 1033>T>273 (0C to 760 C)

Good luck
