采用绝热铜卡量热计法在２８７—１２７３Ｋ的温度范围内测定了不同条件下自焙炭块的热焓．结果表明，尽管自焙条件不同，但热焓的差别在实验温度范围内变化不明显，△Ｈ与实验温度的关系为△Ｈ＝－３３．３１＋１．１１Ｔ＋３．６９×１０~（－４）Ｔ~２＋９．８５×１０~２Ｔ~（－１）质量定压热容与温度的关系为ｃ_ｐ＝１．１１＋７．３８×１０~（－４）Ｔ－９．８５×１０~２Ｔ~（－２）
Enthalpy change, △H, of partially graphitized self-baking carbon block with different graphitization degree has been determined by means of copper calorimeter in temperature range from 14 to 1000℃. It seems that the graphitization degree is not influential to △H of the carbon blocks in the range of the experimental temperature. The temperature dependence of the A△ is expressed as follows:△H=-33.31+1.11T+3.69×10~(-4)T~2+9.85×10~2Ta~(-1) By differential the temperature dependence of the massic heat capacity c_p is repesented as follows:c_P=1.11+7.38×10~(-4)-9.85×10~2T~(-2)
