Product Description

The KS-CGF-BMGH-1200X-S Bridgman Crystal Growth Furnace is a state-of-the-art vertical high-temperature furnace specifically designed for the directional solidification of single crystals and the preparation of high-purity materials. Utilizing the Bridgman-Stockbarger method, this system offers precise control over the crystal growth environment, ensuring high-quality crystal formation with uniform grain structure and minimal defects.
The furnace features a vertically oriented, split-type tubular heating zone capable of reaching temperatures up to 1200°C. It supports a controlled temperature gradient, which is essential for directional solidification and controlled cooling. The furnace is equipped with high-precision temperature controllers with dual-zone regulation, enabling independent management of upper and lower heating elements for stable and repeatable thermal profiles.

At the heart of the system is a motorized crucible-lifting mechanism with adjustable speed, allowing for programmable descent of the sample through the furnace's thermal gradient. This controlled translation of the sample ensures a clean solid-liquid interface for crystal growth, making it ideal for materials such as gallium arsenide, lead iodide, germanium, or selenium-tellurium alloys.
The KS-CGF-BMGH-1200X-S also includes a sealed quartz reaction chamber, allowing for operation under vacuum or inert gas atmosphere. Gas inlets, vacuum ports, and optional gas purging capabilities are provided for a contamination-free environment. The system is compatible with standard Bridgman-type double-tube crucibles, where the material melts in the upper zone and crystallizes in the lower zone as it passes through the temperature gradient.

For user convenience, the furnace is mounted on a robust and mobile frame with locking caster wheels. The control panel is front-mounted and features digital PID controllers, emergency shutoff, programmable ramp/soak functions, and status indicators for safe and intuitive operation. An optional touchscreen controller with recipe storage and USB data logging is available for advanced users.
This system finds wide application in material science laboratories, semiconductor R&D, and academic research institutions working on crystal growth, compound synthesis, and phase transition studies. Its compact footprint, precise control, and reliable thermal performance make it an indispensable tool for anyone involved in the growth of oriented crystals.
With its thoughtful engineering, modular structure, and premium-grade components, the KS-CGF-BMGH-1200X-S represents a perfect fusion of traditional Bridgman growth techniques with modern thermal processing technology. It is manufactured by Luoyang Kunsheng Instrument Equipment Co., Ltd, a trusted provider of advanced thermal systems for scientific and industrial applications.
