Etymology of ALUMINIUM ANTIMONIDE
The word "aluminium antimonide" has its etymology rooted in the names of the elements it comprises.
"Aluminium" derives from the Latin word "alumen", meaning "alum", which is a compound that has been known since ancient times. The element was initially called "alumium" by the British chemist Humphry Davy when he discovered it in the early 19th century. Later, the name was changed to "aluminum" to be consistent with other elements.
"Antimonide" refers to the element antimony. The word "antimony" comes from the Latin term "stibium", which in turn is believed to have its origins from the Egyptian word "msdmt", referring to eye paint or cosmetic powder, as antimony compounds were used in ancient Egypt for eye makeup.
