| titleOfInvention | X-ray fluorescence flux composition |
| abstract | In the x-ray analysis of minerals, ores and other materials, chemicals containing lithium and boron are melted together at high temperatures to produce lithium borate compounds which are then cooled and reduced in size to a powder or coarse material. Such material is known as x-ray flux and is usually represented or specified in the final commercial product as ratios of lithium tetraborate to lithium metaborate. The x-ray is melted with materials to be analyzed and cast into discs which are then analyzed by an x-ray fluorescence spectrograph. In this invention, a lanthanide of the yttrium group has been added and melted with the chemicals containing lithium and boron, such as to function as an internal standard, when the fluxes are mixed and melted with samples to be analyzed. |
