含微金属砭石超微颗粒对光反射率特征及优质砭石颜色分析

Reflectance characteristics of the superfine particles in Bian-stone and high quality Bian-stones' color analysis

砭术作为失传已久的传统医术,具有多种医疗保健的效果,但是现有砭石产品良莠不齐,严重限制了砭术的推广。本文运用岩石学分析测试技术,对不同颜色砭石产品的主要矿物成分以及微量成分做了对比分析。X射线衍射结果表明,黑色和黄褐色砭石中质量分数92%以上为微晶方解石,致密的结构是砭石的热发光和热疗作用的直接原因;拉曼光谱和透射电镜结果表明,黑色和黄褐色砭石中存在微米级和纳米级石墨颗粒,石墨对提高砭石的导电性和热辐射性有重要作用;主次量成分分析表明,黄褐色砭石中黄铁矿的含量要高于黑色砭石,透射电镜结果显示黑色砭石中黄铁矿主要是微米形态存在,黄铁矿的形态对砭石的颜色和热电性有很大影响。综合比较,黑色砭石的理疗效果优于黄褐色和红色砭石,从而认为黑色砭石产品是优质砭具。

As a long-lost traditional chinese medical skill, Bian-stone therapy has a variety of health care effects. But the existing Bian-stone products market chaos is very unfavorable to the promotion of Bian-stone therapy. In this paper,main composition and trace compositions of Bian-stone products with different colors have been compared by using the petrological analytical techniques. It is found that main mineral composition in black and brown Bian-stone products is microcrystalline calcite. A compact calcite structure is the directly reason for thermoluminescence and heat treatment effect of Bian-stone. Trace composition of graphite in the Bian-stone plays an important role in increasing the electrical conductivity and thermal radiation. Pyrite nano particles have a great influence on the color and pyroelectricity of Bian-stone. Through comprehensive comparison, the black Bian-stone has a better therapy effect than the brown and red Bian-stone, which mean that the black Bian-stone products have high quality.
