SECTION B – PERFORMING OPERATIONS; TRANSPORTING


B 22CASTING; POWDER METALLURGY


B 22 FWORKING METALLIC POWDER; MANUFACTURE OF ARTICLES FROM METALLIC POWDER; MAKING METALLIC POWDER (processes or devices for granulating materials in general B01J 2/00; making ceramics by compacting or sintering C04B, e.g. C04B 35/64; for the production of metals as such, see class C22; reduction or decomposition of metal compounds in general C22B; making alloys by powder metallurgy C22C; electrolytic production of metal powder C25C 5/00)


Notes

(1)This subclass covers the making of metallic powder only insofar as powder with specific physical characteristics is made.  [6]

(2)In this subclass, the following terms or expressions are used with the meanings indicated:

 "metallic powder" covers powders containing a substantial proportion of non-metallic material;

 "powder" includes somewhat larger particles which are worked, obtained or behave in a manner similar to powder, e.g. fibres.
