摘要: The quantification of elemental impurities in aluminum oxide powder is important due to its large demand for various industrial applications. One of the techniques to perform such analysis is Laser-Induced Breakdown Spectroscopy (LIBS) and to that end, powders are usually pressed into pellets. However, the density of the powder-compact is often not reported and its effect on the analytical figure-of-merit is unknown. In this work, we study the influence of aluminum oxide powder-compacts density of these pellets on the calibration …
