Feldspar is an alkali metal or alkaline earth metal aluminosilicate mineral such as potassium, sodium or calcium, also known as the Changshi group mineral. Potassium feldspar (K2O·Al2O3·6SiO2), also commonly known as Orthodox, is a monoclinic system, usually fleshy red, white or gray. The potassium feldspar series are mainly feldspar, micro plagioclase, and feldspar.
Market research shows that potassium feldspar powder minerals, in addition to being used as raw materials for the glass industry (about 50-60% of the total amount), account for 30% of the ceramic industry, and the rest are used in chemical industry. Glass flux, ceramic blank ingredients, ceramic glaze, enamel raw materials, abrasives, glass fibers, welding electrodes and other industries. Potash feldspar powder is mainly used in glass and ceramics, and can also be used to prepare potassium fertilizer. Potassium feldspar with good quality is used to manufacture TV imaging glass bulbs. Feldspar is an alkali metal or alkaline earth metal aluminosilicate mineral such as potassium, sodium, calcium or strontium. The crystal structure is a framework structure. Its main components are SiO 2 , Al 2 O 3 , K 2 O, Na 2 O, CaO and the like. The feldspar minerals are the most widely distributed in the earth's crust, accounting for about 50% of the total weight of the crust. They are a ubiquitous rock-forming mineral, 60% of which is found in magma, 30% in metamorphic rocks, and 10% in sedimentary rocks, mainly in clastic rocks, but only when it is quite enriched, feldspar can become Industrial minerals. There are four main components of feldspar: potassium feldspar, albite, anorthite, celsian feldspar. An oxide containing silicon, which also contains aluminum!
In general, pure feldspar is rare in nature. Even minerals known as "potassium feldspar" may be symbiotic or mixed with some albite. The feldspar mineral composed of K-feldspar and albite is generally called alkali feldspar; the feldspar mineral composed of albite and anorthite is called plagioclase; the feldspar mineral composed of anorthite and celsian is called Alkaline earth feldspar. Potassium micro-plagioclase is a kind of potassium feldspar whose crystal system is triclinic. When albite is regularly arranged in the form of potassium feldspar, it is called stripe feldspar. The main components of feldspar powder are SiO 2 , Al 2 O 3 , K 2 O, Na 2 O, CaO, etc., which are used to make ceramic and enamel, glass raw materials according to the parameters of mesh number, whiteness and iron content. Abrasives and the like. The basic structural unit of feldspar  is a tetrahedron composed of four oxygen atoms surrounding a silicon atom or an aluminum atom. Each such tetrahedron shares an oxygen atom with another tetrahedron to form a three-dimensional skeleton. Large radius alkali or alkaline earth metal cations are located in large voids within the framework with coordination numbers of 8 (in monoclinic feldspar) or 9 (in triclinic feldspar). The feldspar crystals are mostly plate-like or plate-like columns extending along a certain crystal axis. The twin crystal phenomenon is very common, and there are more than 20 twin crystal laws. Commonly, there are sodium feldspar law, Manniba, Bavenno, Kasbah, and Sodium feldspar. They are present in triclinic crystals or monoclinic and triclinic crystals, respectively. Feldspar is often milky white, but it is often dyed yellow, brown, light red, dark gray, etc. due to impurities, and some can also have beautiful color change or color. There are two groups of complete cleavage with an angle of 90° (monoclinic system) or nearly 90° (87°) (triclinic system). The specific gravity is between 2.56 and 2.76, which increases with the increase of the An content in the composition, and decreases with the increase of Or. The Mohs hardness is 6 to 6.5. The feldspar rich in potassium or sodium is mainly used in the ceramic industry, the glass industry and the enamel industry; feldspar containing rare elements such as strontium and barium can be used as a mineral raw material for extracting these elements; the beautiful feldspar can be used as decorative stone and secondary And so on.
