以天然膨胀石墨（ENG）多孔材料和纳米碳包铝（Al@C）为添加剂，制备了新型复合氯化锶（SrCl 2）。制作了不同密度和盐质量比的试样，并将其分为平行于压缩方向的圆盘和垂直于压缩方向的平板两种类型。热导率采用激光闪光法测量，渗透率采用Ergun模型测量。结果表明，板状样品的热导率和渗透率优于圆盘样品。当密度为800 kg·m-3时，最大热扩散率可达5.7 mm 2·s-1。相应地，其最高导热系数为2.96 W·m-1·K-1，比普通颗粒状SrCl 2高出约15倍。当密度为400 ~ 600 kg·m-3时，平板和圆盘试样的渗透率分别为9.9 × 10 - 10 m2 ~ 9.89 × 10 - 14 m2和2.91 × 10 - 10 m2 ~ 2.46 × 10 - 14 m2。利用新型复合材料SrCl 2的热质性质，提出并比较了其可能的应用，在模拟不同反应器的性能时显示了各自的优势。
A novel composite strontium chloride (SrCl2) is developed with porous material of expanded natural graphite (ENG) and nanoparticle of carbon coated aluminum (Al@C) as the additives. Samples with different densities and mass ratios of salt are produced and classified into disk and plate types which are parallel and perpendicular to the compression direction, respectively. Thermal conductivity is investigated by laser flash measuring method whereas permeability is tested through Ergun model. It is indicated that with regard to thermal conductivity and permeability, plate samples show the better performance than that of disk samples. The highest thermal diffusivity could reach 5.7 mm2·s−1when the density is 800 kg·m−3. Correspondingly the highest thermal conductivity is 2.96 W·m−1·K−1, which is about 15 times higher than that of ordinary granular SrCl2. Permeability of plate and disk samples range from 9.9 × 10−10m2to 9.89 × 10−14m2and 2.91 × 10−10m2to 2.46 × 10−14m2when the density ranges between 400 kg·m−3and 600 kg·m−3. The possible applications are presented and compared by using heat and mass properties of novel composite SrCl2, which show their respective advantages when simulating the performance for the different reactors.
