Abstract
An improved process for the centrifugal spinning of refractory fibers is described. In the improved process rotor circumferential speeds of at least about 21,000 linear feet per minute (6,400 linear meters per minute) are used. In a preferred embodiment the circumferential surfaces of the rotors are also inclined from being perpendicular to the axis of the molten stream, preferably by about 8.degree. to 20.degree..
