  • Patent number: 6372832
    Abstract: A glycol dispersion of an inorganic powder is provided, which comprises glycol and an inorganic powder dispersed therein, said inorganic powder being surface-treated with a dispersant having a solubility of not less than 5 (g/100 g-water) in water of 20° C., and which contains water and/or methanol in the specific amounts. According to the present invention, it is not required to transport a slurry of water, methanol or glycol, but possible to transport in the form of powder, so that efficiency in transportation is not only enhanced, but a drastic simplification in the production steps and a cost reduction are attainable because neither a distillation apparatus for replacing a solvent such as water and methanol with glycol nor a step of wet-pulverizing is required. Moreover, a glycol dispersion of the present invention is able to reproduce the excellent shape and size of the inorganic particles before drying or in the initial state and therefore has an excellent dispersibility.
