摘要： A method of processing water-sensitive ceramic powders, particularly carbothermically produced aluminum nitride, whereby the ceramic powder is deagglomerated in a dry milling step with addition of an alkylamine which is liquid at room temperature is disclosed. The alkylamine is added in an amount sufficient to produce a monomolecular layer on the surface of the ceramic powder. The deagglomerated powder subsequently is vigorously stirred with a concentrated aqueous solution or dispersion of binder and rapidly and gently dried, preferably by freeze drying. Aluminum nitride powder prepared by this process can be further processed into shaped parts with a high thermal conductivity.

摘要： The invention relates to a process for protecting aluminium nitride AlN powder against decomposition, i.e. hydrolysis in moist atmosphere or in an aqueous medium. The process for the protection of AlN powder against hydrolysis is characterized in that in a solution of orthosilicic acid or other silicic acid or water-soluble salt thereof with a concentration of from 1 x 10 to 5 x 10 mole dm , AlN powder is dispersed up to a mass fraction of 1 to 50 %, its particles having an average size of from 0.1 mu m to 1 mm, and during dispersion this suspension is not heated above the temperature of 85 DEG C. In the case of dispersion by milling, an organic or inorganic oxidizing agent, typically H2O2, is added to this suspension in the quantity of from 0.01 to 0.1 ml per gramme of AlN powder.
