- Up: Chemical element
Oxides
(TODO: discuss major ones here)
Carbon group / group IV / group 14 oxides
- CO2 normally the well known gas but highly explosive when in solid sp3 form (analog to quartz)
- SiO2 quartz and its various known polymorphs (~Mohs 7)
- GeO2 argutite Mohs 6-7 -- germanium is a rather rare element!
- SnO2 cassierite Mohs 6-7
- PbO2 [1] -- alpha-PbO2 scrutinyite -- beta-PbO2 plattnerite (TODO: find out Mohs hardness of PbO2 minerals)
(All those have rutile structure. See page about silicon.)
(TODO: Here maybe some pseudo phase diagrams can be made.)
