Sapphire has a number of remarkable properties, e.g. a high melting point, hardness and wear resistance, transmittance in a wide range of wavelengths, chemical neutrality and mechanical strength. The heat conductance of sapphire is similar to that of metals, yet it is an excellent insulator and retains its basic properties under radiation.
     A wide range of sapphire products can be manufactured using the Stepanov method (EFG).
Tapes, rods and round, square, triangular-selection and other tubes. The parts have been made in the plant without any machining or lapping, by pulling directly from melt by the Stepanov method (EFG), using various tailored formers, appropriate temperature conditions and conditions of process motions, which is the main «Know-How» of the process.
     Now, we are ready to offer production in the form of tapes after growth (tapes width up to 90mm, thickness up to 7mm, length up to 250mm), and also, if necessary, to spend processing (open on preparations, grinding, polishing).
     Sapphire parts of more intricate configuration can be manufactured in the plant subject of the agreement with the Customer.
     Products of improved dimensional accuracy can also be manufactured to special Order.
