Albite

Sodium feldspar is a feldspar, a common feldspar mineral, and sodium aluminosilicate (NaAlSi3O8). Albite is generally a glassy crystal, which can be colorless or white, yellow, red, green or black. It is the raw material for making glass and ceramics. Many rocks have the composition of soda feldspar, which is called rock forming mineral.
It is most common in pegmatite and felsic igneous rocks such as granites, and is also found in low-grade metamorphic rocks, and is found in some sedimentary rocks as authigenic albite. Albite usually forms brittle glass like crystals of various colors.
Sodium feldspar is a series of alkali minerals from the plagioclase solid solution series and alkaline feldspar series. It has three diagonal structures, and silicon and aluminum are tetrahedral coordination, forming larger vacancies (i.e. lattice positions), which are mainly occupied by cationic sodium. Although all silicon and aluminum atoms occupy tetrahedral positions in this structure, their positions are different. At low temperatures, the distribution of silicon and aluminum atoms is highly ordered, and the distribution of atoms is much more chaotic at high temperatures (about 1100 degrees [2000]).
Sodium feldspar: Na2O.Al2O3.6SiO2, in which Na2O 8% is below, K2O 5-6%, Al2O3 16%, SiO2 70%, density 2.605g/cm 3, Moir hardness 6, three cable-stayed system, color white, and melting point 1100 C.
Feldspar is an aluminosilicate mineral of potassium, sodium, calcium, barium and other alkali metals or alkaline earth metals. The crystal structure is a shelf structure. Its main components are SiO2, Al2O3, K2O, Na2O, CaO and so on. Feldspar minerals are the most widely distributed in the earth's crust, accounting for about 50% of the total weight of the earth's crust. They are a common rock forming mineral, of which 60% of them exist in magma, 30% in metamorphic rocks and 10% in sedimentary rocks mainly in clastic rocks, but only when they are fairly rich, the feldspar may become an industrial mineral.
Sodium feldspar is mainly used for making ceramics, soap, tiles, floor tiles, glass, abrasives and so on. It is mainly used in glaze on ceramics.
The most common mineral in the earth's crust is feldspar, which is also found on the moon and meteorites. Within the depth of 15 km underground, feldspar accounts for 60% of the total crustal weight. Feldspar is the main constituent of igneous rock, and is also common in metamorphic rocks and sedimentary rocks. Feldspar is a kind of aluminosilicate mineral containing calcium, sodium and potassium. It has many kinds, such as albite, calcite, barium feldspar, barium feldspar, micro plagioclase, ortho feldspar, and feldspar. They all have glassy luster, various colors, colorless, white, yellow, pink, green, gray, black and so on. Some are transparent and some are translucent. Feldspar itself should be colorless and transparent. It is colored or not completely transparent because it contains other impurities. Some are lumpy, some are plate shaped, some are columnar or needle shaped. Usually in igneous rocks and metamorphic rocks, the feldspar is very small, only 0.1 to 10 millimeters, up to 5~10 centimeters in the porphyry, and some in the pegmatite of some tens of meters.
