摘要
本文报道采用灼烧有效处理一种工业的复合硬垢,用红外光谱和X射线粉末衍射方法,确定该样品由CaC_2O_4·H_2O、α-Fe_2O_3、Ca_(0.9)Mg_(0.1)CO_3固溶体、(Mg,Fe)_2Al_4Si_5O_(18)及炭质物构成。第一次发现堇青石(Mg,Fe)_2Al_4Si_5O_(18)存在于工业污垢中。对方解石Ca_yMg_(1-y)CO_3的Ca/Mg比例和分解温度进行了讨论。
By means of infrared spectrometry and X--ray powder diffraction, the compositions of anindustrial complex hard--deposit were found to be comprised of calcium oxalate CaC_2O_4·H_2O, α-Fe_2O_3, solid solution Ca_(0.9)Mg_(0.1)CO_3, cordierite (Mg, Fe)_2Al_4Si_5O_(18) and carbon laydown. Thepresence of cordierite has not been reported before. The Ca/Mg ratios and the decompositiontemperature of calcite group Ca_yMg_(1-y)CO_3 are discussed.
