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.


The fifth generation MiniFlex is a general purpose X-ray diffractometer that can perform qualitative and quantitative analysis of polycrystalline materials. The MiniFlex is available in two variations. Operating at 600 watts (X-ray tube), the MiniFlex 600 is twice as powerful as other benchtop models, enabling faster analysis and improved overall throughput. Running at 300 watts (X-ray tube), the new MiniFlex 300 does not require an external heat exchanger. Each model is engineered to maximize flexibility in a benchtop package. Read more...
