Description

These are xrdml files able to be opened and analysed by most major manufacturer's XRD software. Bulk powder mineralogy was examined using X-ray diffractometry (XRD). Slags and salt efflorescences were crushed and milled in a tungsten carbide ball mill or agate mortar and pestle respectively. Preparation equipment was cleaned with a quartz sand blank and wiped with ethanol between samples. Powders were mounted on silicon crystal low background holders. Diffractograms were collected from 5° to 90° 2θ using a Malvern Panalytical Aeris diffractometer with PIXcel1D detector, operated at 40 kV, 15 mA with CuKα radiation at a slew rate of 6° 2θ min-1. Diffractograms were analysed using PANalytical HighScore+ software v. 2.2.1 with the 2015 International Centre for Diffraction Data Powder Diffraction File 2 inorganic mineralogical database and the FIZ Karlsruhe GmbH Inorganic Crystal Structure Database. Detection limits depend on crystallinity but were typically 0.1 – 2 wt%.
