DEFINITION

Classification: 264/624

Using organometallic or organosilicon intermediate:

(under subclass 603) Process in which a compound of metal and an organic material, or silicon and an organic material is the transitional precursor to the final shaped product.

(1) Note. Normally, organometallic or organosilicon compounds will decompose before fusing or sintering occurs. Thus, the mere indication of decomposition thereof will not make placement proper under 603, unless the other criteria of Class 264 sintering, vitrifying, or partial fusion is present.
