Abstract: Glass compositions and glass fibers having low dielectric constants and low dissipation factors that may be suitable for use in electronic applications and articles are disclosed. The glass fibers and compositions of the present invention may include between 48.0 to 57.0 weight percent SiO2; between 15.0 and 26.0 weight percent B2O3; between 12.0 and 18.0 weight percent Al2O3; between 3.0 and 8.0 weight percent P2O5; between 0.25 and 7.00 weight percent CaO; 5.0 or less weight percent MgO; and 6.0 or less weight percent TiO2. Further, the glass composition has a glass viscosity of 1000 poise at a temperature greater than 1350 degrees Celsius and a liquidus temperature greater than 1100 degrees Celsius.
