Etymology

Description

It is an element belonging to group 15. It has more than one allotropic formation. The stable form of antimony is a blue-white metal. Yellow and black antimony are unstable nonmetals. It is used in flame resistance, ceramics, enamels and rubber. It is affected by oxidizing acids and halogens. It was first reported by Tholde in 1450.

Language Of Origin

Greek (?) through Medieval English and Latin

Origin Of Word

From the Greek anti meaning "opposite (of something)" and monos meaning "alone", "alone". The element's Latin name is stibium.

Meaning

It has many meanings.

Etymological Description

Since it is believed that it is never found in pure form, it comes from the Greek expressions approximately anti monos meaning "opposite of being alone" or anti monachos meaning "monk killer" (in French folk etymology, anti-moine meaning "monk's curse"). Because most of the first alchemists were monks and antimony was known for its toxicity. The name may also come from the ancient Egyptian phrase Antos Ammon, meaning "flower of God". The symbol Sb comes from Latin stibium, which derives from Greek stibi, which was probably a variant of the word stimmi from Arabic or Egyptian. sdm stands for eye paint. Littré suggests that the first expression comes from *stimmada, which is an alternative accusative case of stimmi (the noun inflected with the main accusative case is the same as the simple case stimmi). The Arabic equivalent of the substance, meaning "cosmetic", can be found as ithmid, athmoud, othmod or uthmod.

Production & Use

Sources

It is found in stibnite (Sb2S3) and valentinite (Sb2O3).

Uses

It is alloyed with other metals to increase their hardness. It is used in the production of several types of semiconductors, plastics and chemicals. Some types of over-the-counter cold and flu medications use antimony compounds in their production.
