Micro-nano tourmaline powder was prepared by using natural Xinjiang tourmaline single crystals as materials.The powder was characterized by XRD,SEM,HRTEM.The influence of tourmaline on water cluster was studied by ~(17)O NMR spectra.The results show that the pyroelectric tourmaline micro-nano particles with perfect crystal structure could be regarded as electric dipoles.The addition of a little amount of tourmaline powder in water leads to lower in half-width of ~(17)O NMR spectra from HW=145.41Hz to HW=81.11Hz.The results suggest that tourmaline powder is a potential material in the improvement of water cluster.
