Tourmaline is a kind of silicate mineral which contains boron as a main element and several other minor elements such as lithium,sodium,iron,magnesium,aluminum,these elements build up the ring structure of silicate minerals. Tourmaline is consisted of lithium tourmaline,black tourmaline and magnesium tourmaline. Taking the black tourmaline as an example,the crystal structure was introduced in this paper and the technologies for preparation of micro-tourmaline and nano-tourmaline powder materials were summarized in this article.%电气石是以含硼为主的锂、钠、铁、镁、铝的环状结构硅酸盐矿物,由锂电气石、铁电气石、镁电气石三种端员组成,本文以铁电气石为例介绍了其晶体结构,并对电气石微米级、纳米级粉体的制备工艺进行了综述.
