Revision as of 12:20, 14 April 2021

This article is a stub. It needs to be expanded.

Advantages:

  • very hard material, very high heat conductivity
  • made out of the extremely common element aluminum (more common than carbon)
  • thermodynamically stable not just metastable thus very heat resistant

Disadvantage:
Crystal structure of less high symmetry than other interesting base materials.
Maybe look at metastable polymorphs at the eventual cost of somewhat less heat resistance?

Note: The page uses leukosapphire instead of just sapphire because
just sapphire is often associated with a blue to black variant where the colour is caused by metal impurities.
A base material for gemstone metamaterial technology would be perfectly impurity free and colorless clear though.
Like a leukosapphire just better.

  • Tistarite Ti2O3 has the same structure.
  • Moissanite is also an extremely heat resistant base material.
  • Diamond is much less heat and oxidation resistant.
  • Both diamond and moissanite have higher crystal structure symmetry than leukosapphire
