Lab Scale Molten Salt Electrolysis Furnace for Metal Refining and Smelting

ZYLAB Lab Scale Molten Salt Electrolysis Furnace

Introduction

The ZYLAB Lab Scale Molten Salt Electrolysis Furnace is a specialized high-temperature system designed for molten salt electrolysis, metal refining, alloy smelting, and electrochemical testing in controlled environments.

Engineered for operation in aggressive molten salt systems such as chlorides, fluorides, nitrates, and carbonates, this furnace ensures excellent thermal stability, corrosion resistance, and atmosphere control, making it ideal for research laboratories, universities, and pilot-scale production.

With a working temperature range of 300°C to 1200°C, the system is widely used in:

• Molten salt electrolysis (metal extraction & purification)

• Alloy smelting and refining

• High-temperature electrochemical experiments

• Corrosion and materials compatibility testing

• Thermal energy storage research (e.g., CSP molten salt systems)

Key Features

1. High Temperature Stability & Uniform Heating

• Resistance wire heating elements with max temperature up to 1200°C

• Dual-zone independent temperature control for excellent thermal uniformity

• High-purity alumina fiber insulation for energy efficiency and low surface temperature

• Precise temperature control accuracy of ±1°C

2. Corrosion-Resistant & Sealed Chamber Design

• Furnace lining options: Al₂O₃ (alumina), graphite, or special alloys

• Resistant to highly corrosive molten salts (Cl⁻, F⁻ systems)

• Sealed chamber with water-cooled flange or metal sealing rings

• Prevents salt volatilization and moisture/oxygen contamination

• Supports inert gas atmosphere (Ar/N₂) for oxygen-free operation

3. Advanced Safety Protection System

• Over-temperature automatic shutdown

• Leakage protection and grounding system

• Optional off-gas treatment or negative pressure exhaust system

• Suitable for reactive or hazardous molten salt environments

4. Electrochemical Testing Capability (Optional)

• Integrated three-electrode ports (working / counter / reference electrodes)

• Compatible with electrochemical workstations

• Supports:

  • Constant current / constant voltage electrolysis

  • Cyclic voltammetry (CV)

  • Electrochemical impedance spectroscopy (EIS)

• Optional high-temperature reference electrodes (Ag/AgCl, Bi/BiCl₃)

5. Intelligent Control & Easy Operation

• PLC touch screen control system

• Multi-step programmable heating curves (heating / holding / cooling)

• Real-time data monitoring (temperature, power, atmosphere)

• USB data export for paperless recording

• Remote monitoring via Wi-Fi or Ethernet (optional)

• Temperature calibration with non-linear correction
