ABSTRACT:
A method for fabricating Y.sub.3 Al.sub.5 O.sub.12 (YAG) fibers from water soluble polymers includes a pre-YAG polymer synthesis, with solution viscosity adjustment followed by fiber spinning and heat treatment. The polymer synthesis employs polar solvents such as water or alcohol with a carboxylic acid containing at least two carboxyl groups.
