Stannate
Encyclopedia
In chemistry the term stannate can refer to compounds of tin (Sn)
Note that stannic acid the formal precursor to stannates does not exist and is actually a hydrate of SnO2
.
The term is also used in naming conventions as a suffix for example the hexachlorostannate ion is SnCl62−.
- orthostannates which contain discrete SnO44− units (e.g. K4SnO4) or have a spinelSpinelSpinel is the magnesium aluminium member of the larger spinel group of minerals. It has the formula MgAl2O4. Balas ruby is an old name for a rose-tinted variety.-Spinel group:...

Tin dioxide
Tin dioxide is the inorganic compound with the formula SnO2. The mineral form of SnO2 is called cassiterite, and this is the main ore of tin. With many other names , this oxide of tin is the most important raw material in tin chemistry...
