Condenser Tube Furnace for Magnesium Purification
Introduction
The Magnesium Purification Tube Furnace is a specialized high-temperature heat treatment device designed for the preparation of high-purity metallic magnesium. Its core technology is based on a sealed heating structure combined with a high-vacuum system, specifically optimized for the physical and chemical characteristics of magnesium (low melting point, high oxidation susceptibility, and high chemical activity).
Utilizing a High Vacuum Environment (≤10Pa), Controllable Atmosphere, and Precision Temperature Control, this equipment efficiently removes impurities such as Iron (Fe), Silicon (Si), Aluminum (Al), and Calcium (Ca). It serves as the core tool for material science laboratories and small-scale pilot production lines seeking to obtain high-quality magnesium sources.
Applications
Due to the excellent corrosion resistance and specific physical properties of purified high-purity magnesium, this equipment is widely used in the following high-tech sectors:
- Aerospace: Used for preparing ultra-high purity magnesium alloys required for spacecraft structural components and lightweight parts. Lowering impurity content significantly enhances mechanical performance, corrosion resistance, and stability under extreme conditions.
- Electronic Information: Suitable for the production of semiconductor packaging, electronic component heat dissipation materials, and magnesium-based hydrogen storage materials. High-purity magnesium reduces impurities that affect electron transmission efficiency and energy storage performance.
- Laboratory & Scientific Research: Provides a precise, controllable purification environment for materials science. It supports research on high-purity magnesium alloy formulas, optimization of purification processes, and mechanisms of impurity impact.
- New Energy: Applied in the purification of magnesium-based battery electrode materials and hydrogen energy storage/transport materials, helping to improve battery energy density and hydrogen storage safety.
- High-End Manufacturing: Used for purifying special magnesium alloys required in precision instruments and medical devices, meeting strict requirements for material purity and consistency.

Features
- Compact Design: The tube furnace structure is significantly more compact than traditional furnaces, making it ideal for environments with limited space.
- Small Footprint: Facilitates easier transport, installation, and storage compared to traditional kilns.
- Double-Shell Structure: Features a double furnace shell with forced air circulation. This design minimizes heat loss and ensures the external surface remains safe to touch.
- PID Programmable Control: The PID temperature controller offers superior precision, supporting both remote and centralized control.
- Dual-Zone Independent Control: Equipped with 2 independent heating zones. Each zone can be set and controlled individually to create a precise temperature gradient required for the purification process.
- High Vacuum Compatibility: Stainless steel vacuum flanges with multiple ports and O-ring seals ensure excellent sealing performance, maintaining high vacuum pressure for critical applications.
Principle
The equipment operates on the Vacuum Sublimation-Condensation Mechanism. It utilizes the significant difference in saturated vapor pressure of various metal elements under the same temperature and vacuum conditions to achieve separation.
- Vacuum Environment: The system is equipped with a professional vacuum setup capable of controlling the furnace tube pressure to ≤10Pa.
- Atmosphere Control: Based on process requirements, the system can introduce inert gases (Argon, Nitrogen) or reducing gases (Hydrogen) to protect the magnesium from oxidation.
- Purification: The raw magnesium is heated in the first zone. Due to the vapor pressure differences, magnesium sublimates while impurities remain or vaporize at different rates. The pure magnesium vapor then travels to the condensation zone (controlled by the second heating zone and water-cooled condenser), where it crystallizes into high-purity metal.
Procedure
- Loading: Raw magnesium material is loaded into the crucible within the high-temperature zone of the 310S Stainless Steel tube.
- Vacuum & Purge: The system is sealed and pumped down to ≤10Pa. If required, the system is purged with inert gas.
- Gradient Heating: The two independent heating zones are activated.
- Zone 1 (Sublimation): Heated to the vaporization temperature of magnesium.
- Zone 2 (Condensation): Maintained at a specific lower temperature to facilitate the deposition of pure magnesium vapor while preventing the condensation of high-vapor-pressure impurities.
- Collection: The purified magnesium crystallizes on the specialized SUS310 condenser.
- Cooling & Retrieval: The furnace is cooled under vacuum or protective gas, and the high-purity magnesium crystals are retrieved.
Advantages
Process Advantages
- High Purification Efficiency: The combination of a ≤10Pa vacuum and dual-zone gradient temperature control significantly lowers the temperature required for impurity vaporization. This ensures a precise thermal field for thorough separation.
- Flux-Free (Green Production): This is a purely physical process requiring no chlorides or chemical fluxes. It avoids flux inclusion contamination and produces no waste gas or slag.
- Superior Product Quality: The resulting crystallized magnesium is dense and oxide-free, requiring no secondary treatment before use.
- Process Flexibility: Parameters (temperature and vacuum) can be quickly adjusted to suit different raw material compositions and target purity levels.
Safety Advantages
- Over-Current Protection: The furnace automatically shuts off power if an over-current is detected.
- Thermocouple Protection: Built-in detection automatically stops heating and triggers an alarm if a thermocouple breaks or fails.
- Power-Off Restart: The KT-TF12-80 supports a resume function. If a power outage occurs, the furnace resumes the heating program automatically once power is restored.
