More Information
Summary:This invention is directed to an alloy, and a method of producing an alloy, of increased resistance to moisture, comprising a melt mixture of at least one phosphate glass, at least one organic thermoplastic or thermosetting polymer, and an amount of a water soluble stabilizer component which provides a source of metal cations having a valency of 2+ or higher. The amount of the stabilizer component added is that amount effective to improve the alloy's resistance to moisture. Preferably, the alloy is comprised of: (a) 5-80% of the matrix material; (b) 15-90% of the phosphate glass; and, (c) 0.1 to 40% of the stabilizer component. Additionally, the metal cations which are found in the stabilizer component and which form part of the insoluble surface layer are preferably selected from the group consisting of Ba2+, Mg2+, Ca2+, A13+, Zn2+, Sr+2 and Fe3+.
