Abstract

Prezenta inventie se refera la un procedeu de obtinere a sulfamatului de nichel, electrolit pentru bai galvanice. Procedeul se bazeaza pe reactia dintre carbonatul bazic de nichel proaspat precipitat sau hidroxidul de nichel proaspat precipitat sau hidroxidul de nichel reactiv, preparat în conditii prestabilite si acidul sulfamic cristalin de puritate înalta si se realizeaza prin amestecarea treptata a acidului sulfamic umed cu precipitatul de carbonat bazic sau hidroxid de nichel, începînd de la temperatura ambianta si pîna la temperaturi în jur de 60 grade C si separarea solutiei obtinute de suspensiile coloidale prin centrifugare.
