Method for determining eta phase copper

A proportion of Cu3Si in a contact mass is determined by treating the mass with an inorganic ammonium salt, which selectively dissolves all forms of copper including free copper in deference to Cu3Si, which is not dissolved. An initial copper content of the contact mass is determined, the contact ma...

More Information
Summary:A proportion of Cu3Si in a contact mass is determined by treating the mass with an inorganic ammonium salt, which selectively dissolves all forms of copper including free copper in deference to Cu3Si, which is not dissolved. An initial copper content of the contact mass is determined, the contact mass is treated with an inorganic ammonium salt composition to extract copper in a molecular form other than Cu3Si and extracted copper is subtracted from the initial copper content.
