Abstract
1521601 Alkali-resistant glass FUJI FIBRE GLASS CO Ltd 20 May 1976 20945/76 Headings C1M and CIH [Also in Division C3] An alkali-resistant glass composition for forming fibres consists essentially of, in molecular weight percent: 58-77% SiO 2 ; 4-11% ZrO 2 ; - 16-24% of at least one alkali metal oxide (e.g. Na 2 O and/or K 2 O) and 0À5-3À5% of at least one oxide of iron or copper (calculated as Fe 2 O 3 and CuO, respectively), the glass not containing more than 4% of Al 2 O 3 contaminant and being free of alkaline earth metal oxide. Fibres of the glass may be used to reinforce Portland or alumina cement.
