Abstract
The feasibility of obtaining granules of high-purity materials from a melt has been demonstrated, using niobium compounds as an example. A distinguishing feature of the method developed is that a concentrated flux of light energy is used to melt high-purity materials in a crucible with a thick protective layer of sintered powder of the material being melted. Moreover, the melt pelletizer is made of ceramics with a protective layer of the material being granulated or a material with a similar chemical composition. Spectral analysis of the composition of the granules obtained from a charge consisting of Nb2O5 and LiNbO3 showed that the content of all the monitored impurities did not increase relative to the initial material. The proposed method can be recommended for prepreparation of mixtures of high-purity materials for growing single crystals or spraying protective coatings.
