Pure and doped single crystal Al2O3 fibers have been grown and evaluated as candidate reinforcements for high-temperature composites. Fibers were grown by the laser heated floating zone process. Growth axes were selected to minimize resolved shear stresses on active slip systems. Growth atmospheres (O2, Ar+O2, Ar+H2) were selected to maximize the quality of the fibers. Dopants include mixtures of Cr2O3, TiO2, and MgO. Fibers have been characterized by orientation, substructure, shape, and mechanical properties. Mechanical properties include room temperature tensile strengths and creep rates at 1700°-1900°C. Growth procedures and properties are reported.
