Abstract
The present invention relates to a high strength light-weight ceramic insulator and a method for manufacture thereof wherein the light-weight ceramic insulator may be used at a high temperature by using a heat-resisting ceramic fiber. A colloidal silica or colloidal alumina which is an inorganic binder, and a methyl cellulose or a liquid-phase organic polymer which is an organic binder are added to an alumina-silica-based fiber containing zirconia, a concentration thereof is adjusted, a slurry is vacuum-molded, and drying and heating are carried out, thereby fabricating the ceramic insulator. Here, it is possible to fabricate the high strength light-weight ceramic insulator by artificially selectively positioning the inorganic binder to a contact point of the fibers.
