ABSTRACT:
An improved process for the formation of alumina-containing fiber is described. The process utilizes alumina having an alpha crystalline phase content in the range of from 5% to 60%, preferably 5% to 35%, as compared to the alpha alumina contents of 75% to 90% of the prior art materials. Use of the low alpha crystalline phase content alumina permits substantial increase in the melt rate of the alumina-containing composition and thus increases production of fiber without any significant deterioration of other processing parameters or properties of the finished fiber.
