摘要
电气石具有永久性自发极化效应,其极化值不受外界电场影响。已经证实电气石颗粒周围存在静电场,而且电气石颗粒能够释放负离子和发射远红外线。利用电气石的这些性质,可将电气石应用于环境与健康领域,如水处理、环保涂料及健康衣料等。因此,电气石是一种很有前景的天然绿色环保材料。
Tourmaline exhibits permanent spontaneous polarization, and the vector of polarization thereofis not influenced by an external electric field. Confirmed is the existence of electrostatic field aroundtourmaline particles. Furthermore, tourmaline particles can release negative ions and emit far-infrared light.With its above properties, tourmaline mineral can be applied to environment and health fields such astreatment of water, environmental protection paints, and health rayon fiber, etc. So tourmaline mineral beinga natural green material has a good prospect.
