Abstract
PURPOSE: To provide the titled glass which is low melting and at low cost and thus suited as matrix for glass fibers without using B2O3 which is expensive and a possible source of pollution, by including a specific molar ratio of SiO2, Al2O3, CaO, and MgO.
CONSTITUTION: In an almino silicate glass represented by the formula RO-Al2O3- SiO2 (R is an alkali earth metal such as Cr or Mg) and essentially consisting of 45W 65mol% of SiO2, 5W20mol% of Al2O3, and 20W45mol% of alkali earth metal oxide, the molar ratio of RO: (Al2O3+SiO2) is specified to 45:55 through 30:70, and RO uses CaO and MgO at the same time. Furthermore, the molar ratio of CaO:MgO is specified to 3:1W3:2; Al2O3: SiO2 to 5:50W20:50. This provides the titled glass.
