·In fact feldspar is the standard for hardness 6 in the Mohs scale Feldspars usually are white or nearly white though they may be clear or light shades of orange or buff They usually have a glassy luster to calcium Ca[Al 2 Si 2 O 8] or sodium to calcium aluminosilicate Pure Na[AlSi 3 O 8] is albite and pure Ca[Al 2 Si 2 O 8] is
·La duret de Mohs est une norme qui indique la duret des minraux propose pour la première fois en 1824 par le minralogiste allemand Friedrich Mohs Cette norme est tablie en utilisant un foret diamant en forme de pyramide pour rayer la surface d un minral la profondeur de la rayure indiquant la duret
·The most common scale for this qualitative test is Mohs scale which is used in mineralogy The Mohs scale of mineral hardness is based on the ability of one natural sample of mineral to scratch another mineral visibly Calcium is has a hardness of approximately Calcium Crystal Structure
The authors also demonstrated that cation exchange reactions controlled the concentration of calcium which in turn controlled the precipitation and dissolution of calcite With calcium being the dominant ion within the bentonite porewaters anhydrite migrated towards the clay/crystalline rock interface via dissolution and precipitation
