摘要：
A new design of dual-vacuum crucible (Staudacher type) is described. The lower and upper part of the crucible is made of tantalum and titanium, respectively. The lower part is heated by a tantalum wire coil inserted into a helix furrow made in a thick-walled insulating cylinder. This cylinder was made from a machineable boron nitride ceramic. By means of this, the crucible may be safely heated in vacuum up to 1600 degrees C.
