Crystal Growing Systems

Reliable, Accurate Control for Crystal Growing

Crystal growers are used for heating gallium arsenide, synthetic rubies, and other crystalline materials in a zirconium or platinum crucible to temperatures of 950° and higher. The primary use of crystal growers is the pulling of gallium arsenide crystals for the laser and IC industries. A crystal grower is designed to have a very accurate control system to maintain a continuous temperature within plus or minus 3°C for a period of up to 6 weeks. Any variance greater than this is the difference between a good crystal and a bad one.
