• 論文の詳細を見る

• An adiabatic calorimeter for the measurements of heat capacities of solid and liquid in the temperature range 80–550 K and the automatic temperature control system are described. The working platinum resistance thermometer is calibrated against a standard thermometer. The measurements of heat capacity of α-Al<SUB>2</SUB>O<SUB>3</SUB> prove the precision to be ±0.3% and give an accuracy of ±0.6%. By means of this calorimeter, heat capacities of anhydrous magnesium acetate have been measured for its glassy and crystalline states around the glass transition point.
