How does tungsten boat work?

In an ideal (vacuum, dry) state, connect the wires at both ends of the tungsten boat and energize, place the low melting point metal in the middle recess, and when its temperature rises below 2000 degrees, the metal will evaporate into a gas and plate on the surface of the workpiece.
