Highly toughened alumina sintered bodies and their manufacturing process |
| abstract |
This invention relates to highly toughened alumina sintered bodies, and the highly toughened alumina sintered bodies are fabricated by sintering an alpha-aluminum oxide powder which is obtained by employing an aluminum hydroxide produced by the Bayer's process as a starting material, and calcining at 900-1200° C. a mixture obtained by adding abrasion powder worn from pulverizing alumina balls or another product to the material, in an amount of 0.01-20 mass % as seed crystals for alpha-aluminum oxide. |
