Feldspar - Mineral Composition, Uses, Types: All the rock-forming feldspars are aluminosilicate minerals with the general formula AT4O8 in which A = potassium, sodium, or calcium (Ca); and T = silicon (Si) and aluminum (Al), with a Si:Al ratio ranging from 3:1 to 1:1. Microcline and orthoclase are potassium feldspars (KAlSi3O8), usually designated …
The specific chemical formula is KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8. The minerals are chemically alert and have a stable pH value. In the Physical properties of Feldspar, we can say that the Feldspars have a monoclinic or a triclinic crystal system and the refractive index of this mineral is 1.518 – 1.526.

Feldspar - Mineralogy, Crystallography, Structure: Sanidine and orthoclase are monoclinic or nearly so; the plagioclase feldspars are triclinic. All, however, have the same fundamental structure: it consists of a …
Feldspar, usually of the potassium or sodium type or mixtures of the two, is principally used in the manufacture of glass and ceramics. In both applications it acts as a flux. Feldspar's alkali content lowers the melting temperature of the mixture, prompting faster melting and fuel savings. Fluxes melt in early stages of the ceramic firing ...

All the natural labradorite sunstones exhibit considerably weaker fluorescence emission than the copper-diffused red labradorite feldspar samples (figure 9). The emission wavelength of the labradorite sunstones from Ponderosa is 388.2–389 nm, and that of the labradorite sunstones from Dust Devil is 392.1–393.5 nm.

Potassium feldspars are an important component of most felsic igneous rocks, pegmatites, low temperature hydrothermal veins and many metamorphic rocks, …
feldspar, any of a group of aluminosilicate minerals that contain calcium, sodium, or potassium. Feldspars make up more than half of Earth's crust, and professional literature about them constitutes a large percentage of the literature of mineralogy.
Feldspar. Feldspar is the most abundant mineral group in the Earth's crust. There are more feldspars (60%) than all the other minerals combined in the outer (13-17) km of the crust 1. Feldspars occur in most igneous and metamorphic rocks. They are less common in sedimentary rocks as they tend to break down to clay minerals in the weathering ...

Deskripsi Mineralogi Feldspar. Sebagai mineral silikat pembentuk batuan, feldspar mempunyai kerangka struktur tektosilikat yang menunjukkan 4 (empat) atom oksigen dalam struktur tetrahedral SiO2 yang dipakai juga oleh struktur tetrahedra lainnya. Kondisi ini menghasilkan kisi-kisi kristal seimbang terutama bila ada kation-kation lain …
Feldspar - Mineralogy, Identification, Uses: Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure), which is manifested by parallel lines on certain cleavage surfaces, whereas grains of alkali feldspars do not. This criterion is not, however, absolute; some …
