A synthetic monocrystalline sapphire monocrystal is a perfect material with a perfect structure. Used in production of light-emitting diodes (LEDs), radio frequency integrated circuits. The high-tech equipment and innovative technologies was used to grow large diameter artificial sapphire crystals weighting up to 95 kg by the Kyropolus method.
