Abstract
The abrasion resistance and tensile strength of asbestos is significantly improved by the addition of significant amounts of metal oxides, such as iron oxide, under conditions to provide at least some surface bonding of the oxides to the surface of the asbestos. The oxides are preferably added during formation of bodies from asbestos dispersions and also impart color to the final product.
