  • Metal silicates, cellulose products, and processes thereof
    Patent number: 6358365
    Abstract: Aqueous composition, including a water-soluble metal silicate complex which includes at least one divalent metal. A process for preparing an aqueous composition including water-soluble metal silicate complex includes combining monovalent cation silicate and divalent metal ions in an aqueous environment to form the water-soluble metal silicate complex. A process of modifying cellulose slurry includes adding an aqueous composition having water-soluble metal silicate complex which includes divalent metal to cellulose slurry. A process for preparing cellulose slurry includes adding monovalent cation silicate to cellulose slurry comprising a sufficient amount of divalent metal ions to combine with the monovalent cation silicate to form water-soluble metal silicate complex. A process of making cellulose product includes: adding an aqueous composition having water-soluble metal silicate complex including divalent metal to cellulose slurry; and forming cellulose product from the cellulose slurry.
