C25B

ELECTROLYTIC OR ELECTROPHORETIC PROCESSES FOR THE PRODUCTION OF COMPOUNDS OR NON-METALS; APPARATUS THEREFOR (anodic or cathodic protection C23F13/00; single-crystal growth C30B)

Introduced: July 1974

Description

C25B covers electrolytic and electrophoretic processes for synthesizing inorganic and organic compounds, as well as non-metallic substances, along with the specialized equipment used in these operations. This includes electrochemical production of chemicals such as halogens, hydrogen, oxygen, acids, bases, salts, and various industrial compounds through direct electrochemical conversion. The classification also encompasses electrophoretic deposition and separation techniques for preparing non-metallic materials. Related electrorefining and electrowinning of metals are excluded and fall under C25C instead.
