Cyberstar Kyropoulos furnaces are offered by ECM Greentech in a flexible design that can match various process requirements in terms of size, heating power and technology. The furnaces can reach working temperature up to 2300°C with a crucible diameter up to 400 mm. All machines are equipped with the precise and stable Cyberstar pulling head having a conversion rate of 0.01 to 100 mm/h translation speed. Based on a top seeding melt growth, Kyropoulos process occurs with a growth interface constantly remaining underneath the surface of the melt where no solid contact happens between the crystal and the crucible. This process enable the growth of large high quality crystals and features a low thermal gradient environment. This a reliable alternative for the growth of materials sensitive to mechanical and thermomechanical stresses such as sapphire crystals.
