C04B 35/565

based on silicon carbide

Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Shaped ceramic products characterised by their composition; Ceramic compositions; Processing powders of inorganic compounds preparatory to the manufacturing of ceramic products > based on non-oxides > based on carbides > based on silicon carbide

CPC:

Shaped ceramic products characterised by their composition ; Ceramics compositions ( containing free metal bonded to carbides, diamond, oxides, borides, nitrides, silicides, e.g. cermets, or other metal compounds, e.g. oxynitrides or sulfides other than as macroscopic reinforcing agents C22C); Processing powders of inorganic compounds preparatory to the manufacturing of ceramic products > based on non-oxide ceramics > based on carbides > based on silicon carbide

Of 5 combined children, 3 exist in both systems.

2 codes exist only in IPC.

IPC defines codes here since 1995.
