  • Method of making highly reactive ion-leachable glass
    Patent number: 4452622
    Abstract: A method is provided for producing a highly reactive, ion-leachable glass for cement compositions. The method contemplates blending together a mixture of ion-leachable, inorganic compositions, forming the blended mixtures into shaped charges, heating the shaped charges to form a homogeneous melt, and finally blowing, in a gaseous mixture, to form partially solidified thin glass fibers. The method uniquely produces glass having a degree of crystallinity of less than 1 percent by weight in crystalline form.
    Type: Grant
    Filed: March 17, 1983
    Date of Patent: June 5, 1984
    Assignee: Johnson & Johnson
