One of the most important properties of tourmaline is its electric property. Tourmalines have spontaneous and permanent poles, which form electrostatic fields around tourmaline particles with c axial planes as two poles. The effect of the electrostatic field of tourmaline can be expressed as follows: under the action of the electrostatic field, water molecules are electrolyzed and hence produce active molecules H 3O + and OH -, in which the former attract impurities or dirts to tourmaline surface, thus purifying the water, whereas the latter combine with water molecules to form negative ions, hence improving living conditions of the mankind; charged particles are attracted by electric fields so that charged particulates in air are attracted to tourmaline and the air is purified. Tourmaline has high mechanical and chemical stability: compared with other minerals with absorption capacities such as zeolite and montmorillonite, tourmaline shows high repeated availability without saturation limit, so its application to the environmental protection field has brilliant prospect.
