Abstract: Mechanochemical effects brought from superfine grinding tourmaline were researched by XRD, FTIR, DTA-TC and carried through contrast tests of the pre and post grinding particle. The crystal lattice has inflation, but it is the lattice distortion category. Ultrafine grinding causes some vibration and fine structure vanishing.The peak present the characteristic which degenerate and wide, the band which [SiO_4] causes vanishes and red shift. The mechanical energy transforms to internal energy of tourmaline, which causes heat absorption effect maximum value temperature to have reduces (1004 ℃ reduces by the original 907 ℃).Indicated to the smallest particle size tourmaline magnetism nature's research, tourmaline coercive force increases .The crystal lattice periodic destruction, enhances the crystal lattice polarity vibration non-simple harmonics effect and improves the tourmaline in certain wavelength range infrared emissivity effectively. Ultrafine powder of tourmaline produces the anoin increases to a certain extent. When the particle size slightly increases to certain extent, the anoin amount reduces.
