Abstract: 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.

Abstract: A machine system and process for producing attrition resistant, controlled release fertilizer is described. In the process, a prewet solution is used to initially coat the plant nutrient to be coated followed by the separate application of the individual components used in the coating. The machine system provides an improved means for uniformly applying a single layer or multiple layers of polymer coatings to the plant nutrient.

Abstract: Method and apparatus for the formation of granules of a larger size or mass of a desired range from a feed stock of smaller particles comprising feeding a meltable powdery material to be granulated, or a non-meltable powdery material with a meltable binder to the surface of a rotating spreader means in the form of a disk or bowl, at least a portion of which has been heated to a temperature above the melting point of the meltable component of the feed material wherein the rate of feeding, the energy input to the spreader means and the rotational speed of the spreader means are controlled so that there is sufficient time for at least a partial melting of the meltable component of the feed material substantially solely by contact with the heated surface of the spreader means, centrifugally spreading the material across the surface of the disk or bowl and dispersing the same from the edge thereof into an atmosphere cooler than the melting temperature to form the granulated product. For certain materials only a part of the powdery feed material is melted forming a liquid film carrying a major portion of substantially unaffected or minimally affected feed material to produce a product comprising individual granules containing a core as the major part of each granule with the original powdery material essentially unchanged maintained in self-sustaining form by a matrix of melted and resolidified particles bonded to each other at their surface.
