DEFINITION

Classification: 264/430

Producing or treating inorganic material, not as pigments, conductive enhancers, or fillers (e.g., ceramic, refractory material, etc.):

(under subclass 405) Processes wherein the energy directly applied is used in the treatment* of or formation of inorganic material other than as pigments, conductive enhancers or fillers.

(1) Note. Inorganic material containing minimal or trace amounts of organic material (e.g., resinous binders, etc.) are properly classified here.

(2) Note. Attention is directed to the definition of Class 260 for the distinction between the term "organic" and "inorganic."
