In chemistry, the term stannate or tinnate refers to compounds of tin (Sn).
Stannic acid (Sn(OH)4), the formal precursor to stannates, does not exist and is actually a hydrate of SnO2.
[1] The term is also used in naming conventions as a suffix; for example the hexachlorostannate ion is SnCl2−6.
In materials science, two kinds of tin oxyanions are distinguished: These materials are semiconductors.
