一般含铁矿物的颜色深暗，对花岗石的装饰美观价值有关键性的影响。花岗石中暗色矿物集中者，石材常呈黑色、绿色系，如摩卡绿（含FeO+Fe2O3：6.43%）、印度黑（含FeO+Fe2O3：13.2%）、南非深黑（含FeO+Fe2O3：2.5%），辛巴威黑（含FeO+Fe2O3：11.5%）等。黄铁矿、白铁矿等含铁矿物嵌入辉长岩中，因而形成了闪烁金光的黑金石材，印度黑金砂即为*显著的例子。含铁矿物在石材中的排列组合，丰富并美化了石材的装饰美观效果，使天然石材色彩变化绚丽，如孔雀绿（含FeO+Fe2O3：6.21%）、森林绿（含FeO+Fe2O3：5.31%）、豹皮花（含FeO+Fe2O3：3.4%）等。宁河柱塞泵型号A10VSO18DRG/31R-P

一般情况下纤维保温材料的纤维排列是后者或接近后者，同样密度条件下，其导热系数要比其它形态的多孔质保温材料的导热系数小得多。填充气体的影响绝热材料中，大部分热量是从孔隙中的气体传导的。绝热材料的热导率在很大程度上决定于填充气体的种类。低温工程中如果填充氦气或，可作为一级近似，认为绝热材料的热导率与这些气体的热导率相当，因为氦气和的热导率都比较大。比热容绝热材料的比热容对于计算绝热结构在冷却与加热时所需要冷量。
