  • Synthetic sapphire is the hardest of all known oxide crystals with a 9 on the Mohs scale and is second in hardness only to diamond.

  • High tension and elasticity tolerances make it extremely wear, scratch and impact resistant.
    Only sapphire and diamond can damage or alter sapphire.

  • Biocompatible with the human body meaning it can be used as medical implants and will not harm living tissue or a living system by not being toxic, injurious, or physiologically reactive and not causing immunological rejection. Even at higher temperatures it doesn't react with organic compounds.

  •  Colorless optical characteristics are superior to any standard glass, with up to a 98.5% transmission.

  • Thermally very stable. Does not lose any of its mechanical or optical qualities from cryogenic to over 2000°C (3632°F).

  • Thermal conductivity greater than other optical materials and most dielectrics (a medium or substance that transmits electric force without conduction).

  • No surface damage and devitrification due to extreme thermal cycling

  • Highly corrosion resistant. More resistant to corrosive chemicals than most standard hard materials available.

  • Combines zero porosity with near total resistance to acids and alkaline substances and only reacts with hydrofluoric acid, phosphoric acid and potassium hydroxide at high temperature of above 300°C (572°F).

  • Does not sag or slump at very high temperatures.
