Aluminum oxide powders |
| abstract |
Collections of particles are described that include crystalline aluminum oxide selected from the group consisting of delta-A12O3 and theta-A12O3. The particles have an average diameter less than about 100 nm. The particles generally have correspondingly large BET surface areas. In certain embodiments, the particle collections are very uniform. In some embodiments, collections of particles include doped aluminum oxides particles with an average diameter less than about 500 nm. The collections of particles can be deposited as coatings. Methods are described for producing desired aluminum oxide particles. |
