Example 1
Electrolytic zirconium powder as the source material was mixed with niobium powder and niobium pentoxide powder, proceeding from the required content of niobium and oxygen in the alloy. The powder mixture was used for pressing briquettes having an inner hole into which a recycled metal bar made of zirconium-niobium alloy was placed. The electrode made in this way was tied round with bars of zirconium iodide and twice melted. The obtained alloy ingot contained, in percent by weight: niobium—0.9, oxygen—0.053, unavoidable impurities, zirconium—the rest.
