| 中文摘要: |
| 偏岭石及其有关的变高岭石过去用一般鉴定结晶矿物的x射线衍射分析定为“非晶质”矿物;后来刘长龄用x射线衍射分析粉末照相高功率长时间拍照,见到有中、低强度的衍射线条(背景发暗).4～4.1(弥散)等多条(偏岭石);4.4Å及2.2Å等(变高岭石),二者有区别(灵敏度高的x射线衍射仪强度曲线分析也有不同(图1),而均属于准晶质或半晶质。今后再鉴定为“非晶质”矿物,不符合事实,显然是错误的。又偏岭石及变高岭石的光学性质等也不是“非晶质”,而具有强非均质性及2V[1][2]. |
| 英文摘要: |
| Clay mineral pianlilnite and metakaolinite were identified as "amorphous"mineral by X ray diffraction analysis to crystalline mineral;then Liu Changling took photograph by high power X ray powder diffraction analysis,found several middle and low strength and scattered lines from 4.4 to 4.1 (pianlinite);4.4Å and 2.2Å (metakaolinite),they are different(sensitive x ray diffractometer strength curve analysis also different),but all belong to paracrystalline. It was identified as "amorphous" mineral, which is not coincided with fact. The optical properties of pianlinite and metakaolinite are not "amorphous" P2, P3, P4 showing strong heterogeneity and ZV[1,2].Liu Changling thinks that samples P2, P3 and P4 were pianlinite in the Hongping’s paper;P5 metakaolinite; Hy Si-Al Spinel+mullite+α-quartz. |
