  • Finely comminuted water-soluble materials and aqueous suspensions thereof
    Patent number: 4367104
    Abstract: Water-soluble crystalline material which has been comminuted in a saturated aqueous solution of the material in the presence of a water-soluble crystal-growth inhibitor having a hydrophobic portion and a hydrophilic portion in its molecular structure is mixed with a deflocculant which inhibits the interaction of the hydrophobic molecular portions whenever the comminuted solid is suspended in water. The viscosity of aqueous suspensions of comminuted solid is thereby stabilized.The invention is especially beneficial in the preparation of aqueous suspensions of finely comminuted ammonium nitrate for use in slurry blasting explosives.
