QF-800 Rapid Melting and Quenching Furnace with 800°C Resistance Coil and Liquid Gallium Quenching Bath
The QF-800 is engineered to facilitate advanced research on rapid solidification and supercooling phenomena by enabling precise melting and quenching of materials within a controlled atmosphere. This system integrates a high-temperature resistance coil furnace capable of reaching 800°C, housed inside a sealed stainless steel vacuum chamber to maintain an inert environment during experiments.
Materials are melted in a quartz crucible and then rapidly injected into a heated liquid gallium bath through pressurized inert gas, typically helium at 10 bar. The gallium bath is maintained at controlled temperatures up to 200°C with magnetic stirring to ensure uniform quenching conditions. This setup allows researchers to study melt quenching and supercooling with precise thermal and atmospheric control.

Configuration & Operating Notes
The system includes the melting furnace, vacuum chamber, quartz crucibles, heated gallium quenching container, and temperature controller with PC interface. Vacuum pumps and related accessories must be acquired separately. Users should verify inert gas pressure limits and follow safety protocols for handling high-temperature molten materials, pressurized gases, and liquid gallium.
