Abstract:

Resources utilization of a variety of industrial solid wastes including steel slag (SS) and carbide slag (CS) is an effective measure that reduces environmental destruction and greenhouse gas emissions. In this work, seven shape-stable phase change materials (SSPCMs) with different mass fractions were prepared by cold compressionhot sintering (CCHS) method utilizing SS and CS as the skeleton material (SM) and NaNO3 as the phase change material (PCM). Research on critical properties of SSPCMs including thermal energy storage properties, microscopic morphology, mechanical properties, chemical compatibility, and economic properties was undertaken. Results indicated that various properties were optimized when the mass ratio of SS, CS, and NaNO3 was 2.5:2.5:5 (SC4). The mechanical strength of sample SC4 was 131.2 MPa, and the optimum thermal energy storage (TES) density in the temperature range of 100 degrees C-400 degrees C was 371.1 J/g. The maximum thermal conductivity of sample SC4 was 1.263 W/(m & sdot;K) after 1307 heating and cooling cycles. The sample SC4 exhibited favorable chemical compatibility and the elements were uniformly distributed in the sample SC4.
