Abstract: Aluminum oxide fibers of the approximate percent composition by weight: Al2O3 61-98% preferably 76-96% SiO2 1-20% preferably 3-15% P2O5 0-10% preferably 0- 5% B2O3 0-10% preferably 0- 5% MgO 0- 5% preferably 0- 1% C 0.1- 4% preferably 0.5-2.8% The fibers are produced by dry spinning a solution containing a neutral or basic aluminum salt of a monobasic lower carboxylic acid, a hydrolyzed silicic acid ester or organoalkoxysilane and polyethylene oxide having a degree of polymerization of at least about 2,000. The product is then heat treated at a temperature between about 400* and 1,800*C. Phosphorus, boron and magnesium may also be present in the solution and end up in the fiber as oxides.
