- Pro: Titanium is common in earths crust (and in space)
- Pro: Hardness is high
- Con? Crystal structure is simple and unit cell is a bit big
Overall a good large scale structural base material for gemstone metamaterial technology.
- Formula: TiO2
- Hardness Mohs 8.5
- Crystal system: Trigonal (the same as sapphire but different unit cell)
- Density ~4.53g/ccm
- Refractive index: ?? – likely quite high
Misc trivia:
Titanium is in a unusual trivalent form here
(as in grossmanite a titanium chain silicate).
