At present, the greater part of artificial sapphire is used as a functional material. However, extremely high production rates are predicted for constructional sapphire as well. This follows from estimations made by specialists in the world’s leading firms. According to the performed analysis, in 70% of cases future prospects for the use of sapphire are tied to its mechanical, thermal, and chemical properties.
