During the production of crystal glass, it is important to remove impurities from the silica sand. Unwanted mineral components are removed by different techniques and by adding different chemicals. Particle size distribution is important for further processing towards a final product. The Phenom ParticleMetric analysis software can be used to measure particle properties based on high-resolution back scattered electron images.
Finding a suitable mining location is very important and also involves scanning electron microscopy. The Phenom electron microscope with EDS and mapping analysis can give an overview of preferred and unwanted mineral components but can also easily image and locate obstructions such as clay particles inside pores.
