EFG process











We are proud to offer new shaped sapphire crystals grown on brand EFG machines.
Besides its common Production processes, RSA proposes high quality sapphire plates, rods and tubes for Optics and many other applications in Mechanics, Chemistry, Biology etc.

We use our Microbeads as starting material for the crucible charge. It confers an extremely good control on the purity of our Ti-free and UV-resistant EFG sapphire.
