A sol-gel method of preparing a powder for use in forming a glass is provided, along with methods of preparing glasses and glass fibers from the powder. The inventive method allows for the incorporation of a wide range of elements and compositions into a homogeneous glass or glass fiber that is substantially free of hydroxide groups. In addition, dopants incorporated into glasses prepared by the inventive method are uniformly distributed throughout the glass structure.

1. A method for preparing powder for use in forming a glass, comprising the steps of:selecting precursor compounds for the glass, wherein at least one of said precursor compounds is a glass-forming material; selecting a solvent for said precursor compounds, wherein said precursor compounds are soluble in said solvent; mixing said precursor compounds in said solvent to form a mixture; hydrolizing said mixture; inducing or permitting said mixture to condense, such that colloidal particles form in said mixture; treating said mixture with bromine to remove water and hydroxide groups from said mixture; drying said mixture to form a powder; and calcining said powder, wherein the calcined powder is suitable for processing into a glass.
