Verfahren zur Herstellung von Schmelztabletten zur Bestimmung des Gehaltes von keramischen Pulvern an Platingruppenmetallen mittels RFA

摘要

The present invention relates to the production of fused beads for determining the platinum group metal content of ceramic powders. The use of a crucible which is free of noble metals and carbon and controlled heating of the material being fused make it possible to produce homogeneous fused beads which allow a measurement accuracy which is five times that achieved using conventional powder pellets employed for this purpose.
