Abstract
The present invention demonstrates a superior, more economical, and scalable process to increase the fluidity of metal powders by surface modification with alkylsilane reagents. This invention discloses that the most efficient process results from treatment with methyltrichlorosilane in hexane. In particular, the fluidity of aluminum powders having mean diameters smaller than 10 micrometers was considerably improved by the process of the present invention. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of the claims.
