摘要

Agglomeration of particulate materials by high energy milling using organic base compound is stearic acid and / or stearates to achieve partu00ecculas agglomerates of fine powders of high escoabilidade compressibility and compacted and sintered high pores. Age.The invention has the following advantages and features: a) employs the use of any type of solvent, which are extremely toxic and flammable normally, which is the case of methanol; (b) is based on the development of an alternative technique of agglomeration of powders to Both the increase of escoabilidade, compressibility.As well as the homogeneity of mixtures of powders of different materials, showing potential application in powder metallurgy and along the deposition techniques for welding; (c) it can be mentioned as the novelty of the invention is the use of organic compounds on the basis of stearic acid And / or a binder stearate as a component.Because such compounds are commonly used as solid lubricants in the field of metallurgy of the powder; and (d) a another novelty lies in the use of the technique of high energy milling to obtain products (mixtures of powders) with high escoabilidade and / or compressibility, as indicated in the FA Bricau00e7u00e3o sintered components of high porosity.
