Summary
A study was made of the conditions of preparation of gadolinium, terbium, dysprosium, erbium, thulium, and lutecium dicarbides by the method of vacuum reduction of oxides of the corresponding metals.
It was established that 1800°C is the optimum temperature for the preparation of these dicarbides. It is assumed that the formation of the dicarbides at the same temperature is linked with the similarity of the electronic structures of the rare-earth metals.
