X-ray Mapping and Chemical Phase Mapping with an Amptek SDD

X-ray Mapping and Chemical Phase Mapping with an Amptek SDD

X-ray mapping (XRM) is the collection of characteristic x-rays as a function of the position of the scanning electron beam on the specimen. This analytical technique provides a high magnification image related to the distribution and relative abundance of elements within a given specimen. Consequently, XRM has become one of the most popular and useful methods of microanalysis and has been widel...

X-Ray mapping and the mineralogy pattern of nickel laterite ore: Bavanat, Fars, Iran

According to the classification of the nickel laterite, this paper describes mineralogy test is to reveal where valuable elements are located in the ore, in which mineralogical form. The purpose of the sieving test was to study if some specific particle size contains most of the valuable metals. Based on its chemical composition nickel laterite is classified as a limonite type and the nickel an...

High-throughput synchrotron X-ray diffraction for combinatorial phase mapping.

Discovery of new materials drives the deployment of new technologies. Complex technological requirements demand precisely tailored material functionalities, and materials scientists are driven to search for these new materials in compositionally complex and often non-equilibrium spaces containing three, four or more elements. The phase behavior of these high-order composition spaces is mostly u...
