  • 矿物中解离度检测方案(扫描电镜)
    Mineral liberation is a critical stage in the production of high quality mineralogical concentrates from their ores. The products (concentrates) must be of a suitable degree of purity for the downstream processes in which they will be used. The original mined ore must be processed via comminution (crushing, grinding and classification) to liberate the desired minerals from it and via concentration (froth flotation, gravity separation, magnetic separation) to enrich the mineral content to the desired level. In order to design, diagnose, monitor and optimise the process, information is needed on the extent to which the valuable mineral grains have been released from the accompanying gangue minerals (degree of liberation) and to which form they are lost in tailings (deportment studies).

  • 金属材料中微观结构检测方案(其它元素分析仪)
    Abstract. This study investigates the changes in radial micro-texture via Kearn’s f-factors during single cold pilger reduction of a titanium Ti-3-2.5 alloy as a result of strain path changes from tooling modifications. EBSD results confirm that the texture intensity as well as the radial f-factors can be increased by modifications of pilgering tooling. In addition a switch between the secondary prism planes which lie normal to the pilger direction in the starting tube to primary prism planes after pilgering has been observed. Material and Experimental The tubes investigated were made from Ti alloy 3Al 2.5V, they were manufactured via hot extrusion and then cold pilgered. The cold pilger process configuration is schematically shown in Figure 1. Two strain paths, shown in the ‘Q‘ factor chart in Figure 2, were used in the manufactiure: texture minimised and texture maximised. They were annealed at 750oC before being cold pilgered and for this investigation they were stress relieved at 530oC for 2 hours prior to EBSD examination. Specimens were extracted from two regions either side of the reduced tube as shown in the schematic Figure 2, mounted in conductive Bakelite and polished mechanically for EBSD examination. The final polish was carried out using vibratory polishes using a mixture of 5:2 colloidal silica, hydrogen peroxide mixture. EBSD examination was conducted using a FEGSEM and OI EBSD Nordlys detector and AZtec Software.

  • 岩石中元素分析检测方案(EBSD系统)
    Introduction Geological samples can be extremely challenging to analyse using EBSD, not only are they non-conductive, but many rocks contain a large number of phases, typically with low symmetry and often producing relatively weak diffraction patterns. The challenge is twofold: firstly the EBSD detector needs to be sensitive enough to acquire good, high resolution EBSPs in a short time period, and secondly the software needs to be able to distinguish reliably between all the minerals present in the sample. In this application we demonstrate the power of the Symmetry&#174; CMOS-based detector coupled with the AZtec&#174; software for the successful analysis of a multiphase, deformed eclogite sample. The extreme sensitivity of Symmetry enables high quality diffraction patterns to be collected in just a few milliseconds, and the advanced indexing algorithms within AZtec, as well as the full integration of EDS data, ensure reliable and accurate measurement of all phases.

  • 金属及合金中表征检测方案(EBSD系统)
    Introduction The groundbreaking Symmetry CMOS-based EBSD detector, together with the powerful AZtec&#174; software, is capable of acquiring EBSD and EDS data at speeds in excess of 3000 indexed patterns per second (pps). These speeds, twice as fast as those achievable with conventional CCD-based detectors, are further enhanced by the fact that extreme pixel-binning of the diffraction patterns is not necessary. This means that the quality of the data collected using Symmetry is significantly better than with CCD-based detectors, both in terms of hit rate and also angular accuracy. In this application note we give examples of how Symmetry can be used to characterise the microstructures in two example metals at high speeds, providing reliable statistics in affordable timescales.

This is primarily because the shells often have physical properties far exceeding those of their constituent minerals: in particular the mother of pearl structure, or “nacre”, consists of small, interlocking tablets of aragonite (orthorhombic CaCO3) separated by organic matrix membranes (Fig. 1).
