Patent number: 10011533Abstract: The present invention is related to the development of a new formulation of electrical grade porcelain having improved mechanical and dielectric characteristics, and whose primary application is in electrical components, such as electric insulators. This invention has as its main object to provide a new alternative to increase the final properties of an electrical grade porcelain, which is related to the incorporation of suitable concentrations of nanosized ceramic oxides, as part of the initial composition of porcelain paste. This new nanotechnology alternative favors an increase in the final properties of electrical grade porcelain, such as flexural strength or cold rupture modulus, as well as dielectric strength, which is due to the incorporation of ceramic oxides such as alumina (?-Al2O3) and zirconia (ZrO2), in micrometer scale (i.e., less than 100 nanometers), favorably modify the microstructure of the base porcelain.Type: GrantFiled: December 1, 2015Date of Patent: July 3, 2018Assignee: PROLEC, S.A. DE C.V.Inventors: José Eulalio Contreras De Leon, Edén Amaral Rodriguez Castellanos
