Abstract

In a process for the preparation of inorganic sample disks for analysis, the sample, in powdered form, is mixed with a powdered reagent flux which has been pre-melted. In an inert gas atmosphere, the mixture is placed in a graphite crucible and heated to a temperature slightly above 1000° C. After the flux dissolves the sample, a homogenous mix is produced. This mix is then poured into a graphite mold, the bottom of which contains a molten pool of an inert metal, such as gold, which acts as a smooth receiving surface. Upon cooling, the material in the mold solidifies, resulting in a glassy disk that can be analyzed. Cooling can be accelerated by making use of a cooling fluid that has a substantially higher thermal capacity than air.
