| titleOfInvention | Alumina sintered body and method for producing the same |
| abstract | (57) [Summary] [Problem] Alumina having a high sintered body density and extremely few pores is produced by using a specific alumina particle and a sintering aid and sintering in an atmospheric pressure atmosphere with excellent productivity. Provide a sintered body. SOLUTION: The maximum particle diameter parallel to the hexagonal lattice plane of α-alumina, which is composed of polyhedral particles having substantially no crushed surface and is a hexagonal close-packed lattice, is D, the particle diameter perpendicular to the hexagonal close-packed lattice plane. Is H, α / alumina particles having a D / H ratio of 0.5 or more and 3.0 or less, wherein the number average particle diameter of the α alumina particles is 0.1 μm or more and 1.0 μm or less, When the cumulative particle size of 10% and 90% from the fine particle side of the particle size distribution are D10 and D90, respectively, the powder is sintered to 99.99% or more alumina powder having a particle size distribution of D90 / D10 of 7 or less. A method for producing an alumina sintered body, comprising adding a binder, and molding, followed by sintering the molded body at atmospheric pressure in a temperature range of 1400 ° C. to 1800 ° C. |
