Crystal growers are used to for heating gallium arsenide, synthetic rubies, and other crystalline materials in a zirconium or platinum crucible to 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 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.
Pillar 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.
