Abstract
A process for polishing both the cadmium and sulfur face of CdS using buffered HCl solutions has been found to produce very smooth crystal surfaces. Use of HCl solutions buffered to a pH between 2.2 and 2.8 to polish the cadmium face is quite effective. An equally effective polishing agent for the sulfur face is a HCl solution buffered to a pH between 0.7 and 1.3.
