<p>PURPOSE:To produce the excellent vapor-deposition material which is not splashed in vapor deposition by producing the material consisting of the metal or alloy having a specified composition by electrolysis. CONSTITUTION:When the vapor-deposition material consisting of the metal or alloy having a composition corresponding to the quality of a vapor-deposited material is produced, an alloy having the desired composition is dissolved in acid to prepare an electrolyte of desired composition, or water-soluble metallic salts are dissolved in water to obtain the electrolyte of desired composition. An insoluble anode of Pt, etc., and a Cu cathode are dipped in the electrolyte, and a current is applied to deposit the metal or alloy having the desired composition on the cathode. The deposit is brought out of the electrolyte, cleaned and dried to obtain the vapor-deposition material. Since the material is not produced by melting and casting a raw material or by powder metallurgy, the material does not contain oxides and nitrides, hence the gas is not liberated by decomposition of the oxide and nitride in vapor deposition, and the material is not splashed in vapor deposition.</p> |
