Conclusions

  1. 1.

    A method has been developed for the comminution and classification of crystalline boron powders.

     
  2. 2.

    Examination of x-ray diffraction photographs of boron powders established that, with decrease in particle size, the intensity of interference lines diminishes and lines representing the long-range order of arrangement of atoms gradually disappear.

     
  3. 3.

    On the basis of results of x-ray diffraction investigations, it is concluded that severe comminution induces amorphization in crystalline boron.
