Solid answers between K-feldspar and albite are referred to as “alkali feldspar”. Geochimica et Cosmochimica Acta: 52: 1097-1112. Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. (1994) The microstructure of perthitic alkali feldspars revealed by hydrofluoric acid etching. Common feldspars include orthoclase (KAlSi3O8), albite (NaAlSi3O8), and anorthite (CaAl2Si2O8). Smith, J.V., MacKenzie, W.S. Canadian Mineralogist: 24: 615-623.

In: Feldspars and Feldspathoids: Structure, Properties and Occurrences (W.L. Feldspar is the name of a large group of rock-forming silicate minerals that make up over 50% of Earths crust. European Journal of Mineralogy: 8: 805-824. : 18: 271-278. The specific gravity of Alkali Feldspar Granite is 2.6-2.7. Feldspar minerals have very similar structures, chemical compositions, and physical properties. (1988) Enthalpies and volumes related to K-Na mixing and Al-Si order/disorder in alkali feldspars.

Physical properties of rocks are used to identify the type of rocks and to discover more about them. Rev. Physical properties of rocks play an important role in determining its applications in various fields. Yoder, Jr., R.A. Yund, Eds., Geochemical Transport and Kinetics. You can also know all the list of rocks in Opaque Rocks, Translucent Rocks and Transparent Rocks. ┗ Albite is an example of a feldspar that can be considered both, alkali as well as plagioclase. Therefore, this mineral is … C 137. Uses of Feldspar ┗ Feldspar contains alumina, which results in an increase in the strength of the manufactured product.
