Conductivity method of alkaline solution in evaluating the spontaneous polarization property of tourmaline

摘要：

　　The spontaneous polarization property of mineral tourmaline was evaluated by the conductivity method of alkaline solution.The conductivity changing rate of the alkaline solution (k) was adopted as the evaluation index.In this paper, the deionized water and alkaline solution were treated by mineral tourmaline powders, respectively.Their conductivity values were tested by a Digital Conductivity Meter.On this basis, the conductivity difference was achieved.The results showed that, the changing rate k increased as the spontaneous polarization property.When 0<k≤2, the spontaneous polarization was weak; when 2<k≤ 10, the spontaneous polarization was stronger; when k > 10, the spontaneous polarization was strongest.
