陶瓷-熔融盐复合相变储能材料
Ceramic-salt based composites for thermal energy storage
摘要
Abstract
This paper reports a study on ceramic based phase change materials (PCM).Sodium nitrate (NaNO3) was used as the PCM,magnesium oxide (MgO) as the ceramic matrix,and different types of carbon materials as the thermal conductivity enhancers (TCE).The composites were fabricated by mixing,compaction,and sintering.The effect of carbon material addition was studied and the morphological and thermophysical properties of the composites were characterized.The results showed that the addition of the TCE could either hinder or enhance the thermal diffusivity of the composites,depending on the type of TCE used.It was found that the thermal energy storage density increased with increasing PCM concentration in the composite.All the composites manufactured were found to be thermally stable up to 500 ℃.关键词
