This system combines a single-chamber glovebox with two distinct furnace architectures: a Well Furnace for bulk electrolysis and a Tube Furnace for precise material synthesis and surface treatment. This integrated approach eliminates "transport lag," ensuring that precursors and synthesized powders never touch ambient moisture (<1 ppm H2O). This platform functions as a closed-loop mini-factory where materials move between states (powder, molten, solid) in a continuous inert stream.

The integrated tube furnace (1700 ℃) is used for the "dry" side of sample processing: (1) Controlled Atmosphere Calcination: Ideal for synthesizing NNFMO or NFPP precursors in a flowing Ar or Ar/H2 environment. (2) Surface Engineering: Can be used for thermal vapor deposition or coating active materials before they are moved to the dry electrode line. (3) Loading Concept: The furnace tube is physically connected to the side of the glovebox. Operator slides the boat of precursors from the box into the tube, seal the flange, and start the program without exposing the sample to the room.

The well furnace (1200 ℃ handles the high-current electrochemical work): (1) Vertical Operation: Allows for large crucibles (up to 5 L) to be lowered into the heating zone. (2) High-Current Feedthroughs: Integrated into the "lid" of the well, supporting the 1000A to 4000A required for pilot-scale sodium production. (3) Heat Management: Water-cooled flanges prevent the glovebox seals from degrading, even if the well is at 1200℃.
