PROCESS FOR PRODUCTION OF SPHERICAL ALUMINUM NITRIDE POWDER, AND SPHERICAL ALUMINUM NITRIDE POWDER PRODUCED BY THE PROCESS |
摘要 |
<p>[Problems] To provide a process capable of efficiently producing a spherical aluminum nitride powder having a size most suited for use as a filler, and having a high sphericalness and a large particle strength. [Means for Solution] A spherical aluminum nitride powder is produced by using a spherical granulated product of an alumina powder or an alumina hydrate powder as a starting material, and feeding the spherical granulated product to the step of reductive nitrogenation so as to be reductively nitrogenated.</p> |
