Betterton Kroll Bismuth

  • Bismuth Element Properties Uses Compounds and Production

    · In the Betterton Kroll process the bismuth containing lead is heated and metallic calcium and magnesium are gently stirred into the molten metal Calcium bismuth and magnesium bismuth compounds having high melting points and low density are formed These intermetallic compounds are easily removed from the lead bath and the bismuth is then freed from the other metals by
