In the study of infrared radiation character, different species of tourmaline and Draviteoccurring in pegmatites from Hebei that are different in granularity and heattreatmenttemperature are chose for infrared radiation ratio testing. The result shows:The infraredradiation ratio of tourmaline powder is above 0.80 when the surrounding temperature is 20℃and the testing temperature is below 100℃;Schorl has a close infrared radiation ratio to Dravite,which is higher than Elbaite;No matter to Dravite or Schorl, as the content of ferric oxideincreases, the infrared radiation ratio decreases;tourmaline's size is smaller, its infraredradiation ratio is higher;after tourmaline is heat-treated under 800℃, its infrared radiation ratiodeclines;Dravite heat-treated at 800℃ has the highest infrared radiation ratio, 0.90;andDravite's structure suffers from destruction above 900℃ heattreatment, so its infrared radiationratio goes down.

在红外辐射特性的研究中，本文选择了不同种属电气石、不同粒度和不同热处理温度河北伟晶岩镁电气石进行红外发射率的测试，结果表明：在环境温度为20℃、测试温度为100℃下，电气石粉体红外发射率均在0.80以上；铁、镁电气石红外发射率相近，且大于锂电气石；不论在铁电气石还是在镁电气石中，随氧化铁质量分数的增加，红外辐射率下降；电气石粒径越小，红外发射率越高；电气石在低于800℃以下温度的热处理后，红外发射率下降，800℃热处理电气石红外发射率最高，为0.90，900℃以上电气石结构遭到破坏，红外发射率降低。

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。

tourmaline：电气石

电气石(Tourmaline)是一种自然矿物,也被認為是一种相当昂的宝石. 它含有独特的放电作用而使身体受益.电气石能放射微量电流、制造远红外线及使湿空气变成负离子.跟机械制成的负离子不同之处是电气石所产生的负离子是完全自然、安全的、沒有任何副作用. 实际很多电气石的好处可归功于它能放射的负离子.
