High Purity Indium Metal Vacuum Distillation Purification Furnace for Semiconductor and Rare Metal Refining

Product Overview

This high-capacity vacuum distillation purification system is engineered for the high-efficiency refining and purification of volatile non-ferrous metals, with a specific focus on high-purity indium processing. By utilizing the differing vapor pressures of constituent metals under high-vacuum conditions, this system effectively separates volatile elements from impurities, delivering premium semiconductor-grade purity. The furnace provides industrial laboratories and advanced manufacturing facilities with the precise control needed to remove critical impurities like lead, copper, iron, and cadmium, helping operators consistently achieve metallurgical purities up to 99.999% or higher.

Optimized for high-throughput material science, semiconductor manufacturing, and new energy sectors, this equipment serves as a cornerstone for advanced material production. The system is designed to seamlessly process large batches of rare metals, providing unmatched thermal uniformity and process consistency. The integrated tilting structural design facilitates convenient material extraction and cleaning, ensuring minimal downtime between production batches and allowing high-volume processing operations to maintain maximum daily efficiency.

Built to withstand demanding industrial environments, this unit incorporates premium-grade structural materials and high-efficiency induction heating elements that guarantee rapid thermal response and uniform heat distribution. The rugged design operates safely under ultimate high-vacuum levels down to the millibar scale, protected by comprehensive physical interlocks and advanced cooling loops. Industrial buyers can rely on this purification platform for continuous, multi-shift production runs with minimal maintenance requirements, making it an excellent investment for modern high-purity metal refining lines.

Key Features

• High-Frequency Induction Heating System: The system utilizes an advanced induction heating coil configuration rated at 160 kW, which couples directly with the graphite or ceramic crucible to ensure extremely rapid heat transfer, superior thermal efficiency, and natural electromagnetic stirring of the melt for homogeneous purification.
• Ultra-High Vacuum Capabilities: Engineered with a multi-stage high-vacuum pumping port, the system achieves ultimate vacuum pressures ranging from 5 Pa down to 5.0 x 10^-3 Pa, significantly decreasing the boiling points of the target metals and preventing any oxidation during the thermal distillation process.
• Optimized 100 kg Crucible Capacity: The massive crucible chamber is specifically scaled to hold up to 100 kg of molten metal based on the density of metallic indium, providing industrial-scale batch capabilities that bridge the gap between pilot-plant research and commercial manufacturing.
• Intelligent HMI and Remote Control Interface: Equipped with a modern, high-definition Human-Machine Interface (HMI) touchscreen controller that supports real-time graphical parameter visualization, comprehensive data saving, historical logging exportable via USB, and complete remote network control options.
• Heavy-Duty 304 Stainless Steel Vacuum Vessel: The main distillation chamber is constructed from heavy-gauge, double-walled 304 stainless steel with integrated water-cooling jackets, ensuring high structural integrity under deep vacuum while maintaining safe exterior touch temperatures.
• Precision Thermocouple Temperature Array: Real-time closed-loop temperature monitoring is handled by high-accuracy industrial thermocouples positioned strategically near the melt zone, delivering rapid, millisecond-fast thermal feedback to the PID controller for stable thermal hold accuracy.
• Multi-Inert Gas Purge Capabilities: The system features integrated gas inlet manifolds designed to support precise flow control of high-purity Argon (Ar), Nitrogen (N2), and other non-corrosive protective gases to manage chamber pressurization, accelerate cooling cycles, or maintain inert operating atmospheres.
• Ergonomic Tilting Chamber Design: Engineered with a heavy-duty structural tilting frame and physical platform stairs, the system enables operators to safely tilt, clean, and harvest purified condensates from the distillation zones with minimal physical strain.
