Abstract

Sposób otrzymywania stopów ren-kobalt na drodze elektrowydzielania z roztworów wodnych charakteryzuje się tym, że do wodnego roztworu siarczanu(VI) kobaltu(II) zawierającego 30 - 50 g/dm3 Co, korzystnie 45 g/dm3 Co podgrzanego do temperatury 30 - 90°C dodaje się wodny roztwór renianu(VII) kobaltu(II) o stężeniu renu 1 - 30 g/dm3 Re, korzystnie 15 g/dm3 Re, w takiej ilości aby stosunek molowy kobaltu do renu był większy niż 2,5 a mniejszy niż 10 oraz jony amonowe, korzystnie w postaci siarczanu(VI) amonu i/lub wodorotlenku amonu w takiej ilości aby stosunek molowy jonów amonowych do renu był większy, bądź równy 0,5, korzystnie 1,0, kwas borowy w ilości od 10 do 45 g/dm3, korzystnie 25 g/dm3 i siarczan(VI) sodu w ilości od 10 do 120 g na każdy 1 dm3 roztworu, korzystnie 15 g/dm3, oraz wodnego roztworu węglanu sodu o stężeniu 2 - 160 g/dm3 i/lub 20 - 40% roztworu wodorotlenku sodu, aż do uzyskania pH roztworu na poziomie 1,8 - 2,5.The method of obtaining ren-cobalt alloys by means of electric separation from aqueous solutions is characterized in that for an aqueous solution of cobalt (II) sulfate containing 30-50 g / dm3 Co, preferably 45 g / dm3 Co heated to a temperature of 30-90 ° An aqueous solution of cobalt (II) rhenium (II) with a rhenium concentration of 1 - 30 g / dm3 Re, preferably 15 g / dm3 Re, is added in an amount such that the molar ratio of cobalt to rhenium is greater than 2.5 and less than 10 and ammonium ions, preferably in the form of ammonium sulfate and / or ammonium hydroxide in such an amount that the molar ratio of ammonium to rhenium is greater than or equal to 0.5, preferably 1.0, boric acid in an amount of 10 to 45 g / dm3, preferably 25 g / dm3 and sodium sulfate in an amount of 10 to 120 g for each 1 dm3 of the solution, preferably 15 g / dm3, and an aqueous solution of sodium carbonate at a concentration of 2 - 160 g / dm3 and / or 20 - 40% sodium hydroxide solution until the solution reaches pH 1.8 - 2.5.
