Abstract

A glass composition, for making glass fibres, consists essentially of the following in percentages by weight:-SiO2, 61-66.5; Al2O3, 2-8; F, 0-1.5; MgO, 2-5; B2O3, 1- <5; BaO, 0-2.75; Na2O+K2O, >14-16 together with CaO such that <FORM:1037851/C1/1> and such that <FORM:1037851/C1/2> Preferably the content of CaO is <7 and the ratio of CaO to MgO is 0.50< <FORM:1037851/C1/3> <0.70, There may be up to 2.5 ZrO2; Fe2O3 is present in the examples in the range 0.30-0.93.
