| 中文摘要 | A research on fabrication of finegrained Al2O3 ceramic at lower sintering temperature was carried out. Al2O3 powder with 50 nm in diameter is compounded with 11.24%Al and 4.75%Fe(mass fraction) by high-energy ball-milling. Al is got from Al powder which is a component of the materials being milled and Fe from steel milling balls and milling jar during the milling. In this way, nearly no impurity is brought into the composite powder during milling. With hot pressing of the composite powder and pure Al2O3 powder, it is proved that Al2O3 powder can be densified at lower sintering temperature when the powder is compounded in this way. Al2OC and AlFe form during sintering process of the composite powder. With the reactive sintering and multiphase sintering mechanisms, finegrained Al2O3 ceramic is fabricated at low sintering temperature. |
