摘要

目的: 对朱砂中HgS含量、形态和晶形进行研究

并与伪品朱砂进行比较。方法: 采用性状、显微、理化鉴别的方法

确立朱砂鉴别特征;采用X-射线衍射和电镜分析法

对朱砂的粒径大小、形貌和晶型进行表征;采用容量分析测定朱砂中HgS含量。结果: 可通过性状、显微、理化特征等的差异鉴别朱砂及其伪品;朱砂有两种变体(α-HgS和β-HgS)

不同产地的朱砂样品具有相对稳定的X-射线单晶衍射特征。结论: 朱砂中HgS含量、形态和晶形是影响朱砂药材质量的重要因素。

Abstract

Objective: Study on HgS content

species and crystal construct of cinnabar. Comparation of cinnabar from its confusable varieties. Method: The cinnabar were identified by macroscopic

microscopic observation

physical and chemical testing. It supplied the bases for identifying the cinnabar. The structure and paticle diameter of cinnabar were investigated with XRD and SEM. HgS contents of cinnabar was determined by volumetric analysis。 Result: Cinnabar from its confusable varieties were identified By difference of macroscopic

microscopic observation

physical and chemical. The cinnabar have two polymorphism(α-HgS and β-HgS). The XRD spectra of HgS nano-powders collected in the different habitats were very consistent with each other. Conclusion: The property of cinnabar have a close relationship with HgS contents and states and crystal shape. It is a main influencing factors of evaluation of cinnabar’ quality.
