摘要 用热敏电阻作加热元件和测温元件,首次系统测定了适合用作相变储热材料的十水合硫酸钠、十水合碳酸钠在温度范围10~80℃的热导率,两者实验热导率的偏差率分别为:±2.56%和±2.41%。同时,报道了十水合硫酸钠、十水合碳酸钠在实验中观测到的熔点分别为30℃和30℃,这些测量值与文献值基本吻合。 The thermal conductivities of Na_(2)SO_(4)·10H_(2)O and Na_(2)CO_(3)·10H_(2)O were measured in the temperature range from 10℃ to 80℃ by means of a calorimeter equipped with a thermistor, since they are considered as potential candidates for the storage of thermal energy. The deviation of the measured thermal conductivities were evaluated to be ±2.56% for Na_(2)SO_(4)·10H_(2)O and ±2.41%for Na_(2)CO_(3)·10H_(2)O, respectively. The melting temperatures were found to be 30 ℃ forNa_(2)SO_(4)·10H_(2)O, 30 ℃ forNa_(2)CO_(3)·10H_(2)O,respectively.The measured melting temperature values agreed basically with the literature values.
