PURPOSE:To obtain easily a large single crystal of tin oxide by using copper as a solvent for tin oxide to be dissolved. CONSTITUTION:Tin oxide as a solute and copper or an alloy of copper and metals such as tin and zinc for depressing the m.p. of copper as a solvent are mixed in the range of (5:95)-(1:99). The mixture is charged into a crucible, etc., and heated and melted in the atmosphere of an inert gas, etc. The melt is heated to a temp. higher than the m.p. of the solvent, and then cooled. The solidified material is taken out, and the solvent is dissolved with an acid or an alkali to obtain a tin oxide single crystal. A large single crystal of tin oxide having >=about 3X2X2mm. crystal size can be obtained by said method. The tin oxide single crystal can be used as a material for electronic parts and an infrared ray absorbent. |
