THERMOELECTRIC CHARACTER OF NATURAL BALCK TOURMALINE
-
摘要: 对产自新疆、内蒙古和云南的天然黑色电气石的化学成分及其对热释电效应的影响进行了测试和分析,对电气石产生热释电效应的机制作了简要阐述。分析表明,不同产地天然电气石的化学成分有较大差异,其中氧化铁含量对热释电效应产生显著影响。随氧化铁含量的增加,热释电效应明显减弱。电气石的热释电效应与其常规物理特性有较好的对应关系。通过检测电气石的密度和折射率即可间接了解电气石的热释电效应。Abstract: The affect of the chemistry on the thermoelectric character of natural black tourmaline is tested, which is from Xinjiang, Inner Mongolia and Yunnan Province. The mechanism of thermoelectric character is designated. It shows that there is much difference in chemical composition of natural tourmaline from different regions, in which the content of ferric oxide will obviously affect the thermoelectric character. With the increase of the content of ferric oxide, the effect of thermoelectricity decreases. The thermoelectric character of tourmaline has better corresponding relation to normal physical character. We can indirectly understand the thermoelectric character of tourmaline through examining the density and refractance.
