DEFINITION

Classification: 264/240

(under subclass 239) Processes in which at least two independent components of a reactive system are combined at the shaping surface.

(1) Note. For processes wherein a chemical reaction, blending or mixing takes place in a mold in the absence of significant molding operations, see the definitions of this class (264) which sets out the line with the chemical composition classes.

82+, for processes which include utilizing a reactive gas or vapor.

183, for processes of extruding into a reactive bath.

301+, accretion from bulk, for initially coating a form with a coagulating material then a material to be coagulated or vice versa. 646, for processes which include utilizing a reactive atmosphere other than air, per se, during sintering to convert precursor to ceramic materials.
