    摘要: Ceramic fibers of alumina modified with zirconia or hafnia derived from soluble salts of the metal are made by first polymerizing a mixture of alumina and aqueous aluminum chlorohydroxide before addition of the metal oxide precursor. Subsequent concentration and spinning steps are carried out at low temperatures.
