Crystal Growing

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

ABP has been supplying equipment for this application since 1981 when we introduced our first design as part of the Crystal Grower line with a 50 kW 10 kHz induction heating Crystal Grower. 

Features include:

• Precision Power Control Circuitry
• Coil Current Control
• UPS or Autostart for Control Circuitry
• Coil Current Feedback
• 4 to 20 mA Control
• Secialized Output Configuration
• Line Monitor Circuitry
• Integral Heat Station
