Apatite milling method

  • High-energy ball milling technique for ZnO nanoparticles ...

     · In this new method a magnet is placed close to the cell to apply a strong magnetic pulling force on the magnetic milling balls, and therefore the impact energy is much higher than the conventional ball milling energy. In addition, different milling actions and intensities can be achieved by adjusting the cell rotation rate and the magnet position.

  • How is apatite mined? | Yahoo Answers

     · The two stages of reclamation are contouring and revegetation. Contouring is the stage in which the mined land is reshaped to resemble pre-mining topography and drainage. The mine areas are contoured using the removed overburden, topsoil and mill tailings. Revegetation provides for the replacement of native habitat. This may require reforestation.

  • Apatite - Wikipedia

    Apatite is the defining mineral for 5 on the Mohs scale. Hydroxyapatite, also known as hydroxylapatite, is the major component of tooth enamel and bone mineral. A relatively rare form of apatite in which most of the OH groups are absent and containing many carbonate and acid phosphate substitutions is a large component of bone material.

    The solid-state transformations of the initial and HEM-activated apatite are examined by TG–DTA analyses. It is found that the thermal stability of the activated samples decreases as compared to the initial sample. This is related to the increased defectivity of the apatite structure during the high-energy milling shown by the XRD data.
