Prepare dry, moisture-resistant aluminum nitride powder that is uniformly coated with an yttrium-containing compound by (a) thoroughly mixing a slurry containing aluminum nitride powder, an yttrium-containing compound, and a solvent for the yttrium-containing compound in the absence of any surfactant and (b) removing the solvent from the slurry. The dry moisture-resistant aluminum nitride powder may be used in aqueous formulations to make ceramic articles. |
