Title: Enostopenjski postopek izdelave kompozitnega keramičnega grelca [SL], One-Stage Process of Manufacturing Composite Ceramic Heater [EN]
Description: The subject of invention is a one-stage process of manufacturing composite ceramic heater before sintering powder mixtures of silicon nitride (Si3N4), Zirconium dioxode (Zn02) and oxide additives (Y203, Al203, Re203, …) for sintering and organic additions to the design, while during sintering in an inert atmosphere of nitrogen or argon on the surface of the composite with the reaction of Si3 N4 and ZrO2 forms ZrN, while core product remains unreacted. After sintering the product has the right mix insulating and conductive ceramic components, and good mechanical, thermal and electrical properties.
