Abstract
Intense chemical reaction of beryllium ceramic crucibles with alloys of metals containing f-elements is established using optical absorption spectra, PCL, x-ray diffraction, x-ray-photoelectron spectroscopy, and electron probe in inert and reducing atmospheres (at high temperatures). Beryllium oxide in the diffusion zone is occasionally reduced to the metallic state, which leads to the destruction of ceramic crucible walls. This restricts the use of the specified crucibles in melting alloys containing rare-earth metals.
