    • A method of determining a quantity of amorphous SiC2-containing impurities in a montmorillonite clay sample comprising the steps of: (a) analyzing the clay sample to determine the weight percent of SiO2 contained in the clay sample; (b) analyzing the clay sample for non-montmorillonite SiO2-containing crystalline components; (c) calculating the weight percent of SiO2 from step (a) that is derived from the montmorillonite and amorphous SiQ2-containing impurities by lowering the weight percent of SiO2 in step (a) based on the non-montmorillonite SiO2-containing crystalline impurities found in step (b); and (d) determining the amorphous SiO2-containing impurity portion of the SiO2 calculated in step (c) by further lowering the amount of SiO2 from step (c) until the amount of montmorillonite-derived SiO2 is consistent with one or more properties of the clay sample, the amount of further lowering being proportional to an amount of amorphous SiO2-containing impurities contained in the clay sample.
    • 一种测定蒙脱石粘土样品中含无定形SiC 2的杂质的量的方法,包括以下步骤:(a)分析粘土样品以确定粘土样品中所含的SiO 2的重量百分比;(b)分析粘土样品 非蒙脱土SiO 2的结晶成分;(c)通过降低步骤(a)中SiO 2的重量百分比来计算源自蒙脱土和含有无定形SiQ 2的杂质的步骤(a)中SiO 2的重量百分比,基于 在步骤(b)中发现的非蒙脱石SiO 2结晶杂质; 和(d)通过进一步降低步骤(c)中的SiO 2的量直到由蒙脱石衍生的SiO 2的量与所述SiO 2的一个或多个性质一致来确定在步骤(c)中计算出的SiO 2的无定形SiO 2杂质部分 粘土样品,进一步降低的量与粘土样品中所含的无定形SiO 2杂质的量成比例。
