'''电气石粉'''是把电气石原矿经过去除杂质后，经过机械粉碎得到的粉体。电气石也叫托玛琳。电气石(tourmaline) 化学通式为NaR3Al6Si6O18BO33(OH,F)4，晶体属三方晶系的一族环状结构[[硅酸盐]]矿物的总称。式中R代表[[金属]]阳离子，当R为Fe2+时，构成黑色晶体电气石。电气石晶体呈近三角形的柱状，两端晶形不同，柱面具纵纹，常呈柱状、针状、放射状和块状集合体。[[玻璃光泽]]，断口[[松脂光泽]]，半透明至透明。无解理。摩氏硬度7-7.5，比重2.98-3.20。有[[压电性]]和[[热电性]]。<ref>[https://wenku.so.com/d/2b19ffdbd85b816ef4f4eedd6dcf69d9 电气石粉最新开发的用途有以下六点.doc ],360文库 , 2021年4月4日</ref>
