堇青石
堇青石 (2MgO·2Al2O3·5SiO2)、堇青石（矿物学）或堇青石（宝石学）是镁铁铝环硅酸盐。 (2MgO·2Al2O3·5SiO2)，铁几乎总是存在，并且在富镁堇青石和富铁硅藻土之间存在固溶体，其系列式为：(Mg,Fe)2Al 3(Si5Al2O18) to (Fe,Mg)2Al3(Si 5Al2O18). 存在一种高温多晶型物，indialite，它与绿柱石同构，Al在(Si,Al)中随机分布 6O18环
产品代码 : CE-Mg2Al4Si5O18-NN-CU
Cordierite combines great thermal shock properties, low thermal expansion rate, and good electrical insulation. It is an excellent fit for inexpensive insulators used in manufacturing and durable goods. Cordierite (mineralogy) or iolite (gemology) is a magnesium iron aluminium cyclosilicate. Iron is almost always present and a solid solution exists
