Definitions
- the intermediate spaces between the conductor tubes 1, 2 and 3 can contain a gas or can be evacuated. Advantageously it is filled with insulating material, however.
- the vessel of a device for crucible-free zone-melting wherein the upper end of the current supply is provided with the induction heating coil 13, is evacuated or filled with protective gas such as a noble gas, it is advantageous for the intermediate spaces between the conductor tubes 1 to 3 to be filled with insulating material which has a Shore hardness in the range of l to I00 and an extensibility of at least 20 percent, and when a gas-tight adhesive connection is provided between the insulating material and the surface of the conductor tubes.
