Abstract
This report deals with the methods for melting and casting zirconium. Reference is made to the manner of heating, furnace design, crucible materials, and methods of casting. For the experiments, a high‐frequency furnace, an arc furnace, and a split‐tube graphite‐resistor furnace were used. Preference is given the latter for vacuum fusion, while the high‐frequency and the arc furnaces are well adapted for melting in a noble gas atmosphere. The crucible materials are discussed, and the melting in graphite and the casting of ingots are described.
