  • Treated glass fibers
    Patent number: 4105492
    Abstract: A method of preparing glass fibers having a surface enriched by zirconium dioxide thereon, comprising the steps of: applying an aqueous solution of zirconyl carbonate to the surface of the glass fibers, keeping the fibers wetted under ambient conditions for a period of time to effect ion exchange with water extractable ions in the surface of the glass, and evaporate the water to leave the coated glass fibers. The coated glass fibers are especially suited for reinforcing cementitious materials.
