Fine ceramics

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 borides, nitrides or silicides > based on silicon nitride > Fine ceramics

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 borides, nitrides, or silicides > based on silicon nitride > Fine ceramics

Of 2 combined children, 0 exist in both systems.
