The invention relates to a preparation method of a special ceramic ignition device. The preparation method comprises blending 70-78wt% of silicon nitride and additives such as 2-3wt% of yttrium oxide, 5-6wt% of titanium carbide, 1-2wt% of titanium powder, 2-4wt% of aluminum oxide, 2-3wt% of titanium carbide, 2-3wt% of silicon carbide and 3-4wt% of boron nitride, putting the materials into a stirring mill, adding 150% of distilled water into the mixture, carrying out stirring for 15h, drying the mixture through an oven at a temperature of 180 DEG C, putting the dried mixture into a screening machine, carrying out uniform screening, putting tungsten filaments into a mill, pressing the tungsten filaments in the silicon nitride powder, putting the powder into a graphite mold frame, putting the graphite mold frame into a hot-pressing furnace, putting the sintered product into a clamp, welding a nickel wire ring and a lead for electric conduction, putting the qualified product into an aluminum oxide base, carrying out pouring with a silica filler and assembling the poured product and a metal part. The special ceramic ignition device has a long life, stable power, insulativity and environmental friendliness.
Description
technical field [0001] The invention relates to a preparation method of a special ceramic ignition device, which is used in the auto parts industry, civil industry, aviation industry and other industries, mainly for ignition and preheating. Background technique [0002] Most of the existing products of the same kind are metal products, which have poor high-temperature oxidation resistance and are easy to oxidize, thereby shortening the service life of the metal igniter, and the product surface is prone to rust, which leads to a decline in the ignition function of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a preparation method of a special ceramic ignition device. The technical solution adopted by the present invention to solve the technical problem is: the structure of the present invention includes an inner sleeve, an outer cover, a screw , base, g...
