【摘要】 以桂林电气石和阿尔泰电气石为原料,研究了它们产生的空气负离子性能．用红外光谱仪、X 射线衍射仪、扫描电镜对这两种电气石进行了分析表征．结果表明：桂林电气石为铁电气石,平均能够产生空气负离子692个/cm~3,相对增加空气负离子394个/cm~3；阿尔泰电气石为铁镁电气石,平均能够产生空气负离子 935个/cm~3,相对增加623个/cm~3；两种电气石吸收或辐射的主要红外波段基本一致,都存在比较多的红外活性键,但是阿尔泰电气石在7．39μm 处多出现了一个 B —O 键辐射或吸收峰．更多还原

【Abstract】 Tourmalines from Guilin and Aertai area were researched on negative-air-ions properties and characterized by IR,XRD and SEM.The results showed tourmaline from Guilin was Fe-tourmaline,which could produce average 692 negative air ions and relative increasing 394 negative air ions per cubic centimeter;that tourmaline from Aertai was ferridravite,which could bring average 935 negative air ions and relative increasing 623 negative air ions per cubic centimeter;meanwhile,both of tourmalines were basically consistent in main infrared wavelength absorbed or eradiated by tourmalines and existed in quite a few infrared active bond,but tourmaline from Aertai appeared an added absorbed or eradiated peak of B—O bond in the wavelength of 7.39μm.更多还原
