ABSTRACT:
A novel optical fiber connector part is provided which comprises a ferrule having a capillary hole for holding an optical fiber, the ferrule being formed from a zirconia-alumina composite oxide containing yttria at a content ranging from 2 to 4 mol % in zirconia. In the optical fiber connector part, a sleeve for connecting and holding the ferrule may be formed from zirconia and/or a zirconia-alumina composite oxide. A process for producing the optical fiber connector part is provided wherein the granular zirconia-alumina composed of a particulate zirconia-alumina mixture having an average particle diameter of not more than 1 .mu.m is used as raw material. The granular zirconia-alumina preferably contains alumina at a content ranging from 0.1% to 50% by weight. The process comprises spray-drying a slurry containing a particulate zirconia-alumina mixture having an average particle diameter of not more than 1 .mu.m. The ferrule has a stable spherical face at the tip, and will not deform during long-term connection. The granular zirconia-alumina has excellent sintering characteristics.
