Volume-average particle diameter

  "id": "MLC-T-CHM-012622",
  "term": "Volume-average particle diameter",
  "field": "Chemistry",
  "definition": "The mean particle diameter obtained by averaging the cubes of the diameters over all particles, weighted by number, and taking the cube root, which equals the diameter of a sphere with the mean particle volume. It is weighted toward the larger particles of a dispersion because the diameter enters cubed. Electron microscopy counts and laser diffraction can supply the data.",
