天然黑色电气石红外辐射特性研究

对新疆、内蒙古和云南等地的天然黑色电气石红外辐射特性进行了测试和分析，结果表明：不同产地和不同矿区的黑色电气石化学成分差异较大，其中氧化铁含量对红外辐射率具有明显影响，随氧化铁含量的增加，红外辐射率下降；天然黑色电气石在还原性气氛条件下进行热处理后，可具有比远红外陶瓷粉料更高的红外比辐射率值，其红外峰值辐照与维恩定律具有很好的对应关系，在室温下峰值辐射波长为9．5μm左右。研究认为，天然黑色电气石在保暖、保健等领域具有很高的实际应用价值。

Natural Black Tourmalines'Character of Infrared Radiation

Natural black tourmalines are tested and analyzed,which are produced in Sin Jiang,Inner Mongolia and Yunnan.The results show that chemical composition of black tourmalines differ greatly from their producing areas and diggings.And the content of ferric oxide affects the infrared radiation ratio apparently:along with the content's increasing,the ratio decreases.Having a heat treatment under a deoxidized atmosphere,natural black tourmalines can take on higher value of the infrared radiation ratio than infrared ceramics powders,and the peak value of the infrared radiation correspond well to Wayne Law,at room temperature it being 9.0 um.The research advances that natural black tourmalines have great potentials in practical application fields,such as health care,keeping warm,and so on.
