The invention relates to the technical field of friction welding stirring heads, and discloses a sialon ceramic friction welding stirring head and a production method thereof. The friction welding stirring head is creatively produced from sialon ceramic, the sialon ceramic has good toughness, very high hardness, very high wear resistance and very high high-temperature oxidation resistance, and raw materials of the sialon ceramic have low prices and wide sources. A traditional ceramic technology and high-molecular chemistry are organically combined, a high-molecular polymer polymerization technology is introduced to a ceramic production technology, and a gel injection molding technology is adopted, so compared with other molding technologies, the method disclosed in the invention has the substantial advantages of short production time, low die and device requirements, low cost, and high structure and component designability; the density of the above product is uniform; a green body has a high strength, and is convenient for machining; and the method is especially suitable for realizing near-net-shape forming, realizes small product shape limitation, can be used to produce complex profiled parts, and is universal and economic.
