Abstract
A ceramic spinneret used for producing manufactured fibers and formed from a fine grained, essentially pure structural ceramic such as aluminum oxide, zirconium oxide, composites of aluminum oxide and zirconium oxide known as toughed ceramics, silicon nitride, silicon carbide, or any fine grained essentially pure structural ceramic. Such spinnerets are formed as a single piece and contain non-circular capillaries suitable for forming shaped or void containing fibers.
