  • Patent number: 5427705
    Abstract: The inventive composition contains salt, calcium magnesium acetate (CMA) and sodium silicate, and may optionally contain sodium ferrocyanide, diatomaceous earth, and/or other materials. The composition is useful for facilitating the melting and removal of snow and ice, and is stable and non-corrosive. The inclusion of both CMA and sodium silicate in the salt composition provides better corrosion resistance than can be obtained by the inclusion of comparable quantities of either CMA or sodium silicate alone. The inventive salt composition is considerably less expensive to manufacture than CMA-containing salt compositions which provide comparable corrosion resistance.
