Crystal structure: Cubic or ortorhombic near cubic

Earth alkali titanate perovskites:

• CaTiO₃ – Perovskite – Calcium titanate – ~4.0g/ccm – Mohs 5.5 – (coordinates)
• BaTiO₃ – 6.0g/ccm – (de)
• SrTiO₃ – Strontium titanate (mineral Tausonite) – cubic – Mohs 6.0-6.5 – (de) – Eu doped used as a strong green phosphorescent (glow powder)

• ZrTiO₃ ??
• PbTiO₃ – Lead_titanate – toxic & water soluble, bad combination
• – ZrTiO₃ to PbTiO₃ – Lead zirconium titanate – strongly piezoelectric

Exotic

Not stable under low pressure (need small scale ultra high pressure encapsulation)
