Abstract
A process for forming a metal or non-metal carbide fiber comprising the steps of stabilizing a fiber comprising a carbon forming polymer and a metal or non-metal oxide or a mixture of more than 50% by weight of said oxide and a metal or non-metal to form a stabilized fiber; carbonizing the stabilized fiber to form a fiber comprising carbon and a metal or non-metal oxide or a mixture of said oxide and a metal or non-metal; reacting the carbon and metal or non-metal oxide or mixture of said oxide and metal or non-metal to form a fiber comprising a metal or non-metal carbide; and sintering the fiber comprising said metal or non-metal carbide to form a fiber having a density of greater than about 70% of the theoretical density of said metal or non-metal carbide.
