The use of crucible with a particular material depends on the melting point
of the material to be evaporated. Generally high temperature resistant
material with good refractory properties are promising candidates. Some
commonly available crucibles are made of Tungsten, Boron nitride, Alumina,
Molybdenum, Tantalum and diamond.

Hope this information helps.
