KYROPOULOS

Kyropoulos crystal growth machine

ECM Lab Solutions offers several Cyberstar Kyropoulos furnaces varying in size and heating power. The heating technology can be inductive or resistive depending on the process requirements. The size of the crucible can reach up to 400mm diameter and a working temperature of 2300°C.

These machines are all equipped with the precise and stable Cyberstar pulling head having a conversion rate of 0.01 to 100 mm/h translation speed. Kyropoulos Crystal growth process is a top seeding melt growth method where the growth interface is constantly beneath the surface of the melt without any solid contact between the crystal and the crucible.

Known for its high quality, relatively large crystals, this method is characterized by a consistent low thermal gradient growth environment. It is commonly used for the growth of materials sensitive to mechanical and thermo-mechanical stress, which is usually difficult to obtain by other crystal growth methods.  The seed is dipped on the surface of the melt to allow the growth of the crystal inside.
