Niobate

Part of speech: noun

Definitions

1. A chemical compound containing the niobate ion, usually comprising niobium and oxygen with other metallic elements; a salt or ester derived from niobic acid; a material used in specialized chemical or industrial applications
2. A substance consisting of niobium oxoanions combined with metallic cations, forming crystalline or amorphous structures; salts formed from niobic acid with various metals; compounds significant in materials science and chemistry
3. A compound characterized by the presence of niobium combined with oxygen and metals, resulting in salts or esters of niobic acid; utilized in advanced ceramics or electronic components; belonging to a class of oxometalates involving niobium

Etymology: Niobium itself has a more dramatic naming story than its salts do. It was named after Niobe, the mythological daughter of Tantalus, because its discoverer found it closely tangled with tantalum, and Niobe was Tantalus's child. The word "niobate" follows from that chain: it is built from "niobic acid," the acid associated with niobium, with the suffix "-ate" added to name the salts it forms. The suffix does the chemical work. "-ate" comes ultimately from Latin "-atus," which in chemistry marks a salt or ester derived from an acid whose name ends in "-ic." So "sulphuric" gives "sulphate," and "niobic" gives "niobate," following the same pattern. The Latin ending passed into English through the Proto-Italic and Latin stages in the source, and chemists adopted it as a standard label for oxyanion salts.
