摘要
电气石颗粒周围存在静电场,永久性自发极化效应使其具有热电性、压电性、天然电极性、辐射红外线、释放负离子等性能。开发电气石的功能属性,将其应用于环境保护、医疗保健、电磁屏蔽等领域,将产生巨大的经济和社会价值。
Tourmaline is one of most important functional minerals. Tourmaline possess of natural permanent polarity and not is affected by additional electric field, some research testify that tourmaline can form electric field around its particles. In addition, tourmaline particles have some functional properties such as thermoelectricity, piezoelectricity, natural spontaneous polarity, radiate far-infrared ray, release anionic etc. Investigate and exploit tourmaline＇s these functional properties, and apply it to environmental protection, medical treatment, electromagnetic interference shielding etc, it has great social and economical value in protecting environ- ment and promoting people＇s health.
