摘要: 将RD-1型量热计的样品管改装成能测量金属氢化反应热效应的量热系统,量热计常数经电能标定,峰高法和面积法所测结果的相对精度为0.5—1%。

Abstract: Using a heat conducting type automatic calorimeter made by Sichuan University as a basic element, we have constructed a new calorimetric vessel for the determination of heat effects of gas-solid interface reactions. The calorimeter was coupled with a set of gas-solid equilibration apparatus and heat constants of the system were caliberated by galvano-metric methods. The experimental equipments and manipulation procedures are described, and the accuracy of the measuring technique by peak height and envelopment area hase been found to within 0.5-1%. The system has been used for the determination of the relative partial molar enthalpies of the absorption of H3 by LaNi5, and the results are in good agreement with that cited in the literature[2]. It is believed that this calorimetric system can be used for the investigation of heat effects of reaction between intermetallic compounds and hydrogen.
