The thermal behaviors in the present high temperature adiabatic calorimeter were analzyed theoretically to devise the improvement of the precision of the apparatus and the adaptability at high temperature above 1100℃. It was confirmed that the influence of the heat transfer by radiation on the total thermal leakage out of the calorimeter block is predominant, and so the leakage might increase in proportion to the third power of absolute temperature. The calculated value of the leakage at 1000℃ is about 6 cal/min and agrees fairly well with the observed value. It was considered that the leakage might be reduced through the improvement of the adiabatic controlling. It might be expected to elevate the precision of experiment remarkably by reforming the present apparatus with single adiabatic wall into the type with double ones. With this improved calorimeter, it might be expected to reduce the leakage below 0.6 cal/min at 1300℃.
