Feldspar-group minerals are a significant group of rock-forming minerals that are primarily composed of aluminosilicates of sodium, potassium, and calcium. They are characterized by their crystalline structure, which typically exhibits a framework of tetrahedra formed by silicon and aluminum atoms. These minerals are generally divided into two main categories: alkali feldspars (such as orthoclase and microcline) and plagioclase feldspars, which vary in composition from sodium-rich to calcium-rich varieties. Feldspar minerals are known for their hardness, typically ranking between 6 and 6.5 on the Mohs scale, and they exhibit a vitreous to pearly luster. They are commonly found in igneous, metamorphic, and sedimentary rocks and play a crucial role in the geological processes of the Earth. Additionally, feldspars are important in various industrial applications, including ceramics, glass production, and as fillers in paints and plastics. The CAS number 68476-25-5 refers to a specific mixture of feldspar minerals, indicating its relevance in various industrial contexts.
