Abstract

This invention consists of chilling a platten for the intermediate polishing of cross-sections. The platten can be made of any material. The cooling of the platten can be accomplished by either of two methods. The first method consists of pouring a cold liquid such as liquid nitrogen along the edge of the platten in the bowl. The second method consists of internally cooling the platten with a chilled liquid. The purpose of chilling the platten is to remove the heat generated during polishing from the sample surface in order to reduce and eliminate the amount of smearing and mechanical/plastic deformation of soft low-melting point materials. This invention was developed for use in the Minimet' polisher by Buehler, Ltd. but can be used for any size platten.
