The Hard Truth About Particle Contamination

In contrast, quartz has a Vickers hardness of approximately 1,200 (7 on the Mohs scale), which is roughly times harder than chrome steel. Quartz was chosen for comparison because it is one of the most abundant minerals in soil (primarily sand). Silicadioxide crystals are commonly referred to as quartz and can be found in most soils.
