Minerals and Metals Analysis

Particle characterisation by image analysis using the Morphologi G3 from Malvern Instruments is proving valuable in a diverse range of mineral and metals applications. The shape and size of mineral and metal particles can play an important role in determining process efficiency and final product quality in applications spanning the measurement of metal powders for Metal Injection Moulding (MIM) to the production of mineral-based cosmetics. Now, a new and freely available audiovisual presentation ‘Measuring the morphology of minerals and metals’ and an application note ‘Comparison of metal powders produced by different atomisation processes for metal injection moulding using the Morphologi G3’, which are both accessed via the Malvern website, provide additional applications information and case examples.

The downloadable application note describes a detailed case study. Here the Morphologi G3 is used to reveal how atomised metal powders with similar particle size distributions, produced by two different atomizing processes, can have very different shape properties, and how such parameters can be assessed.

The Morphologi G3 from Malvern Instruments is a fully automated image analysis-based particle characterisation system that delivers particle size and shape information for wet and dry samples. Capable of analysing particles from 0.5 to 10000 μm, and capturing microscope quality images of hundreds of thousands of particles in just a few minutes, the Morphologi G3 measures a wide range of size and shape parameters. Single-click measurements minimise user intervention, saving time and eliminating user bias, while powerful software tools make it easy to visualise, classify and filter results.
