Composition of barite: A universal material

Barite is primarily used in the oil drilling industry for lubrication of their drill bits during the drilling and cutting process. It is also used in a variety of other applications including pigments, inks, plastics and X-rays. The density and color of this natural mineral make this a valuable product. However, in each application the purity and composition of the contaminants should be closely monitored as it may alter the properties and function of the barite material. Shown in the provided diffractogram is a sample of barite collected on the MiniFlex. Using the Whole Pattern Fitting (WPF) program available in Jade, this material was identified to be 91.7% barite with contaminants of quartz and calcite.


New sixth generation MiniFlex X-ray diffractometer (XRD) is a multipurpose analytical instrument that can determine: phase identification and quantification, percent (%) crystallinity, crystallite size and strain, lattice parameter refinement, Rietveld refinement, and molecular structure. It is widely used in research, especially in material science and chemistry, as well as in industry for research and quality control. It is the newest addition to MiniFlex series of benchtop X-ray diffraction analyzers from Rigaku, which began with the introduction of the original MiniFlex system decades ago. Read more...
