Disclosed is a high-heat-conduction ceramic heater. The high-heat-conduction ceramic heater is prepared by the following raw materials in parts by weight: 6 to 11 parts of potash feldspar, 4 to 10 parts of friction powder, 3 to 10 parts of a polypropylene fiber, 4 to 8 parts of cryolite, 2 to 7 parts of copper oxide, 3 to 10 parts of quartz, 1 to 5 parts of zinc oxide, 4 to 11 parts of dolomite dust, 2 to 6 parts of ceramic powder, 6 to 10 parts of A1C13, 4 to 10 parts of a glass fiber, 2 to 8 parts of aluminum oxide, 4.5 to 9 parts of diethylene glycol, 4 to 6 parts of talcum, 2 to 5 parts of amphibole powder, 5 to 9 parts of a zircon product, 9 to 14 parts of wollastonite and 2 to 5 parts of alumina. The high-heat-conduction ceramic heater has the following advantages: the ceramic heater is good in thermal conductivity and high in thermal conversion efficiency, at the same time, is long in service life and is corrosion-resistant and magnetic-field-resistant.
