Full Title
Full titles differ between systems:
IPC:
Catalysts, in general, characterised by their form or physical properties > characterised by dimensions, e.g. grain size
CPC:
Catalysts, in general, characterised by their form or physical properties > characterised by dimensions, e.g. grain size (in a colloidal state B01J35/23; crystallite size B01J35/77)
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
IPC defines codes here since 2024.
