Method for preparing α-alumina nano powder |
| abstract |
The present invention relates to a preparation method of α-alumina nano powder, and more particularly to a preparation method of α-alumina nano powder that has a uniform particle shape and size distribution, is capable of being produced at a low temperature, and contains less than 20 ppm of alkali metals such as Na and K. the α-alumina nano powder is prepared by glycolating aluminium alkoxide in glycol solution containing the α-iron oxide or α-alumina nucleation seed and carrying out glyco thermal reaction. |
