【摘要】 <正> 测定分子筛的结晶度有多种方法,而以无定形强度卡法测得的值为准确。因它可不用标样而客观地将结晶峰与无定形峰分开,而结晶峰的测量是采用多个峰的加和。本文是运用无定形强度卡法对A型分子筛的结晶度的研究。 1 原理更多还原

【Abstract】 A method of an amorphous strength card used to measure the absolute crystallinity of zeolite A from their X-ray diffraction patterns is introduced. The method shows that it is not necessary to use a standard sample for the measurement of the crystallinity of zeolite A.更多还原
