Phase Transformation Temperature Adjustment of Calcium Chloride Hexahydrate

Abstract:

Phase change temperature adjustment of calcium chloride hexahydrate added small quantity of barium hydroxide and strontium chloride hexahydrate was researched. The experimental results demonstrated that, its phase change temperature adjustment could be achieved by means of adding excess water, and its suitable adjustment range of phase change temperature was 21.76°C-26.16°C as the proportion of the added excess water was 0-10% by weight. According to the calculation equation gained by the theoretical regression of the experimental results, its phase change temperature with different proportions of excess water may be forecasted during the suitable adjustment range of phase change temperature. This characteristic is of important application value for temperature control in greenhouse or air conditioning etc.
