NOVELTY – The electrically conducting ceramic material preparation method involves adding 4.3 ml of 3.5 mol/l hydrochloric acid to 76.0 ml of tetraethyl orthosilicate solution and agitating the solution for 3 hours at 333 K. 15 ml of zirconium tetrabutoxide and 3 ml of 3.5 mol/l hydrochloric acid, were added to mixture. 6 g of graphite powder of 99.9% purity is added to mixture and left for 8 hours at room temperature. The solvent is evaporated slowly at 333 K in open container until a gel is formed and remaining solvent is evaporated increasing temperature to 393 k, resulting in a completely dry gel. USE – Method for preparation of electrically conducting ceramic material. DETAILED DESCRIPTION – The dry gel is crushed and left in 1 mol/l nitric acid for 15 hours, followed by washing with deionized water and vacuum drying at 343 k for 2 hours. An INDEPENDENT CLAIM is also included for the electrically conducting ceramic material, which comprises 60% silicon dioxide, 20% zirconium dioxide and 20% graphite or 50% silicon dioxide, 20% zirconium dioxide and 30% graphite. DESCRIPTION OF DRAWING(S) – The drawing shows a schematic view of a copper wire with electrically conducting ceramic material.
