Sapphire windows, wafers and flats are one of the hardest and most scratch resistant products available; far more durable than any type of glass. Synthetic sapphire's high modulus of elasticity and high tensile strength make it extremely durable and impact resistant, second only to diamond in mechanical and wear resistant properties.
Sapphire windows and wafers transmit more into the infrared and ultraviolet range than standard glass windows. In addition, sapphire windows and wafers are more temperature and chemical resistant than any other transparent (and most non-transparent) materials. Sapphire is also a great thermal conductor and a superior dielectric material with a high dielectric constant and low loss tangent.
