Intermetallic phases between tungsten and rare earth elements have only been found for the W-Ce system. Two phases exist in this system, which are formed by peritectic reactions; one of them is believed to be W2Ce, “Elliott” (1965), p. 314.

Flame spectra of the rare-earth elements
Spectrochimica Acta, 1962Abstract The rare-earth elements, including scandium and yttrium, emit intense line spectra when absolute ethanol solutions of rare-earth halide or perchlorate salts are aspirated into fuel-rich, oxy-acetylene flames. Recordings of the spectra are given, along with the exact wavelengths of about 1200 of the strongest lines.
