  • Patent number: 6670293
    Abstract: A kit and a method for making a porous cement which self sets to hydroxyapatite and has an interconnected porosity is produced by mixing a calcium source and a phosphate source with a carbonate source and mixing this powdered component with a liquid component having an acid component. The liquid component comprises water or an aqueous solution containing an acid. The acid and the carbonate react to form carbon dioxide thereby producing an interconnected porosity in the normally solid self-hardening bone cement. The method requires only a relatively low weight percent of the acid and base to be mixed with the liquid and powder cement components.

  • Publication number: 20020029724
    Abstract: An article and method for its manufacture are described. The article is preferably a ladle used in the manufacture of metals and receives molten metal for further chemical processing in the ladle or for transportation. The ladle is transparent to a wide range of electromagnetic radiation wavelengths which allows the metal to be heated or stirred by induction without heating the ladle itself. The ladle is made of glass fibers and an inorganic cement, and this provides strength along with high temperature resistance. The article is manufactured by winding glass fiber around a mandrel, the glass fiber having an inorganic cement adhered to it. In one technique, the cement is provided on the fiber as an aqueous slurry, and the product is allowed to air cure after winding. In a second technique, the cement is adhered to the fiber by electrostatic attraction.
