Abstract: Tourmaline is a kind of cyclosilicate mineral,and has great application value because of its piezoelectricity and far-infrared resistance.Present status of surface modification of tourmaline powder was summarized from  the aspects such as modification methods,processes,surface modifiers,and formula.Modification principles and basic technological processes of mechanochemical surface modification method and surface organic coating method were introduced in detail.Applications of modified tourmaline powder in the fields of water treatment,medicinal and health care,energy saving and environmental protection as well as spinning were also generally described.At last,the development tendency of modification of tourmaline powder and its application potentials were prospected.

Key words: tourmaline, surface modification, silicate
