X-ray diffraction analysis is a convenient and important route to investigate crystalline materials. With powder materials, calcium carbonate as target, the effects of scatter slit, soller slit and receiving slit of Bruker D8 ADVANCE diffractometer on the diffraction pattern based on information, such as the background intensity, peak height, intensity and full width at half maximum, which provide the evidence for slits selection.
X-ray diffraction analysis is a convenient and important route to investigate crystalline materials. With mesoporous materials, Al-SBA-15 as target, the effects of scatter slit, soller slit and receiving slit of Bruker D8 ADVANCE diffractometer on the small-angle diffraction pattern based on information, such as the background intensity, peak height, intensity and full width at half maximum, which provide the evidence for slits selection.
Wood-plastic composites were produced by heating, blending and extruding with recycled plastics and wood fiber as chief raw materials and some thermoplastic resin as the additive. The compounding formula and producing craft were researched and optimized. The influence of the ratio of wood fiber and additives was examined. Wood-plastics composites with excellent performance were produced.
Powder X-ray diffraction (XRD) is one of the primary techniques used to characterize solid state materials. But there is not a sample holder which can be fit into the sample carrier of the Bruker D8-Advance x-ray powder diffractometer for flakiness and block samples test. In this article, we will design, manufacture and evaluate a sample holder for flakiness and block samples. Materials of the holder are steel, glass and plasticine etc. The holder is low cost, easy to be processed, convenience to prepare the samples, and accurately obtain the best analytical results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
