Abstract

Improved glass batch compositions and processes of fiberizing the compositions to form fibers are provided. The batch of the present composition can include: 40-60 wt % SiO2; 15-50 wt % Al2O3; 0-30 wt % MgO; 0-25 wt % CaO; 0-5 wt % Li2O; 0-9 wt % B2O3; and 0-5 wt % Na2O. The fibers formed of the compositions may have a Young's modulus of greater than 82.7 GPa (12 MPSI). The fibers may also have good biosolubility (kdis), of at least 100 ng/cm2/hour.
