Apparatus for chemically polishing crystals
Abstract
Abstract A method and apparatus for chemically polishing crystals of the group II(b) - VI(a) system of the periodic table using a mixture consisting essentially of bromine and methanol with the bromine being present in the amount within the range of about 0.05 to about 10 percent by volume of the total solution of the mixture and forming a moving fluid film of the mixture to polish the crystal surface is shown. The apparatus includes a polishing dish and crystal support disk which supports the crystal to be polished and positions the crystal surface to be polished adjacent a plate which forms part of the polishing dish and a dispensing means which supplies a polishing solution between the plate and crystal surface for establishing a fluid film therebetween to chemically polish the crystal surface.
