Introduced: January 1980
Full Title
Full titles differ between systems:
IPC:
Single-crystal growth by zone-melting; Refining by zone-melting > Heating of the molten zone > by irradiation or electric discharge
CPC:
Single-crystal growth by zone-melting; Refining by zone-melting (C30B17/00 takes precedence; by changing the cross-section of the treated solid C30B15/00; under a protective fluid C30B27/00; for the growth of homogeneous polycrystalline material with defined structure C30B28/00) > Heating of the molten zone > by irradiation or electric discharge
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
IPC defines codes here since 1980.
