High-purity alumina ceramic shaft and preparation method thereof
Abstract The present application belongs to the technical field of ceramic materials, and specifically relates to a high-purity alumina ceramic shaft and a preparation method thereof. The high-purity alumina ceramic shaft includes a ceramic shaft body; the ceramic shaft body includes a hollow cylinder and has a length of 90.4 mm to 90.6 mm and an inner diameter of 6 mm; the ceramic shaft body is provided with a circular wing that divides the ceramic shaft body into an upper part and a lower part; the upper part has a length of 19.90 mm to 20.10 mm and an outer diameter of 24.96 mm to 24.98 mm and the lower part has a length of 62.5 mm to 62.6 mm and an outer diameter of 24.96 mm to 24.98 mm; the wing has an outer diameter of 38.40 mm to 38.60 mm; and the upper part is a truncated body obtained from the cylinder after one side of the cylinder is truncated by a vertical plane, and one side of the upper part is a vertical rectangular surface. The ceramic shaft in the present application is made of alumina with a purity of 5 N, where, granulation is conducted with ultrapure water (UPW) with an electrical conductivity of 0.06 S/M, allowing the ceramic shaft to have a high alumina purity and a narrow particle size distribution curve. Therefore, the ceramic shaft exhibits strong resistance to oxidation, abrasion, high and low temperatures, and thermal expansion and contraction, and has the functions of anti-vibration, anti-acceleration shock, water resistance, acid resistance, and the like.
