    • Abstract

       

      The process for forming the anodic oxide on Hg0·8Cd0·2Te using a constant voltage d.c. source is studied. The electrolyte is composed of 0·1 N KOH, 90% ethylene glycol and 10% water. Good, uniform, transparent and reproducible films are obtained when the pH of the solution is adjusted between 7 and 8 by using oxalic acid. The anodic oxide film shows an anti-reflection effect. HCl and NH4OH etch the oxide well and give a smooth polished surface of Hg0·8Cd0·2Te.
