PROCESS FOR PRODUCING ALPHA-ALUMINA POWDER |
| abstract |
Disclosed is a method for producing an α-alumina powder which comprises the steps of: (1) spraying a metal compound having a width at half height (Ho) of a main peak in the diagram. of X-ray diffraction (XRD) to obtain a seed crystal having a width at half the height (H) of the main peak in the XRD diagram, in the presence of a sputtering agent, (2) mixing the obtained seed crystal with a aluminum salt, (3) calcining the mixture, andwhere the H / Ho ratio is 1.06 or more. |
