'Sb-containing' originates from modern chemical notation combining the chemical symbol 'Sb' (for antimony) with the English present-participle adjective-form 'containing'.

'Sb' (the chemical symbol) derives from Latin 'stibium'; the phrase 'containing antimony' in technical writing was later shortened and hyphenated to the form 'Sb-containing' for concision in scientific literature.

Initially it meant 'containing antimony' in plain phrasing, and this core meaning has remained the same while the notation shifted toward the compact hyphenated form used in modern technical contexts.
