Title: GLAZE FOR A CERAMIC ARTICLE
Abstract:
The glaze is prepared from the following raw materials in percentage by weight: Fire Clay 10% - 25%, Feldspar 30% - 40 %, Sand 30% - 40%, Calcium Silicate 8% - 12%, Graphane (i.e., disordered crystalline and hydrogenated double bounded Carbon) 5% - 15% or C-doped Boron Nitride (CBN) 5% - 15%, various metal oxides as pigments and water. This glaze is applied on the standard glazing operation in the ceramic insulator manufacturing process and is fired in a controlled inert-gas atmosphere.
