Berlinite
Berlinite ( aluminium phosphate, chemical formula AlPO4 or Al(PO4)) is a rare high-temperature hydrothermal or metasomatic phosphate mineral. It has the same crystal structure as quartz with a low temperature polytype isostructural with α–quartz and a high temperature polytype isostructural with β–quartz. Berlinite can vary from colorless to greyish or pale pink and has translucent crystals. It was first described in 1868 for an occurrence in the Västanå iron mine, Scania, Sweden and named for Nils Johan Berlin (1812–1891) of Lund University. It occurs as a rare mineral in high-temperature hydrothermal or metasomatic deposits. Associated minerals include augelite, attakolite, kyanite, pyrophyllite, scorzalite, lazulite, gatumbaite, burangaite, amblygonite, phosphosiderite, purpurite, apatite, muscovite, quartz, hematite in granite pegmatites. It also occurs with alunite, aragonite, collophane, crandallite, francoanellite, gypsum, huntite, hydromagnesite, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium Phosphate
Aluminium phosphate is a chemical compound. In nature it occurs as the mineral berlinite. Many synthetic forms of aluminium phosphate are known. They have framework structures similar to zeolites and some are used as catalysts, ion-exchangers or molecular sieves. Commercial aluminium phosphate gel is available. Berlinite AlPO4 is isoelectronic with Si2O4, silicon dioxide. Berlinite looks like quartz and has a structure that is similar to quartz with silicon replaced by Al and P. The AlO4 and PO4 tetrahedra alternate. Like quartz, AlPO4 exhibits chirality and piezoelectric properties. When heated, crystalline AlPO4 (berlinite) converts to tridymite and cristobalite forms, and this mirrors the behaviour of silicon dioxide. Uses Molecular sieves There are many types of aluminium phosphate molecular sieves, generically known as "ALPOs". The first ones were reported in 1982. They all share the same chemical composition of AlPO4 and have framework structures with microporous cavities. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nils Johan Berlin
Nils Johan Berlin (Nils Johannes Berlin) (18 February 1812 – 27 December 1891) was a Swedish chemist and physician, who held various professorships at the University of Lund from 1843 to 1864. Berlin was the first chemist who took the initiative to write a textbook on elementary science, the purpose being to provide basic science education for the general public. His chemistry research emphasized the study of minerals, especially the newly-discovered rare earths, having devised means of separating yttrium and erbium. The mineral berlinite (a type of aluminium phosphate) is named after him. Berlin became a member of the Royal Swedish Academy of Sciences in 1844. Education Berlin graduated from the University of Uppsala with a doctor of philosophy in 1833, having studied under the tutelage of Jöns Jacob Berzelius. He completed a doctor of medicine degree in 1837, also at the University of Uppsala. Academic career Berlin held a number of faculty positions at the University of ...

Västanå
Västanå is a village situated in Bromölla Municipality, Skåne County, Sweden with 130 inhabitants in 2005. Västanå iron mine In 1800 an iron ore deposit was discovered and mining began in 1804. Till the closure in 1917, 1500 tonnes of iron ore were mined. Several new minerals were discovered in that mine. For example Christian Wilhelm Blomstrand discovered berlinite trolleite augelite Augelite is an aluminium phosphate mineral with formula: Al2( P O4)(O H)3.

Scorzalite
Scorzalite () is a dark blue phosphate mineral containing iron, magnesium, and aluminium phosphate. Scorzalite forms one endmember of a solid solution series with the lighter, more magnesium-rich lazulite. Scorzalite crystallizes in the monoclinic system in a dipyramidal form. It has a Mohs hardness of 5.5-6 and a specific gravity of 3.4. It is infusible and insoluble in water, and only slightly soluble in warm hydrochloric acid. Occurrence It was first described in 1947 for an occurrence in the granite pegmatite in the Córrego Frio mine, Linópolis, Doce valley, Minas Gerais, Brazil. It was named for the Brazilian geologist Everisto Pena Scorza (1899–1969). It occurs as a secondary phase in pegmatites and kyanite (aluminium-rich) quartzites.

Phosphosiderite
Phosphosiderite is a rare mineral named for its main components, phosphate and iron. The siderite at the end of phosphosiderite comes from the word "sideros", the Greek word for iron. It was published in 1890, and has been a valid species since pre- IMA. It is an IMA approved mineral which got grandfathered, meaning its name is still believed to refer to an existing species. Properties Phosphosiderite is a member of the metavariscite group, and probably forms a complete series with metavariscite. It is the dimorph of strengite. It is totally soluble in Hydrochloric acid and nearly insoluble in nitric acid. It is usually cut into a cabochon shape for jewelry, and used as an ornamental stone. It mainly consists of oxygen (51.38%), iron (29.89%) and phosphorus (16.58%), but contains hydrogen (2.16%) as well. Colors Phosphosiderite is often found in a bright orchid-purple tint with yellow-colored streaks. The vein-like streaks found in the stone are known as cacoxenite. Four o ...

Amblygonite
Amblygonite () is a fluorophosphate mineral, , composed of lithium, sodium, aluminium, phosphate, fluoride and hydroxide. The mineral occurs in pegmatite deposits and is easily mistaken for albite and other feldspars. Its density, cleavage and flame test for lithium are diagnostic. Amblygonite forms a series with ''montebrasite'', the low fluorine endmember. Geologic occurrence is in granite pegmatites, high-temperature tin veins, and greisens. Amblygonite occurs with spodumene, apatite, lepidolite, tourmaline, and other lithium-bearing minerals in pegmatite veins. It contains about 10% lithium, and has been utilized as a source of lithium. The chief commercial sources have historically been the deposits of California and France. History The mineral was first discovered in Saxony by August Breithaupt in 1817, and named by him from the Greek ''amblus'', blunt, and ''gonia'', angle, because of the obtuse angle between the cleavages. Later it was found at Montebras, Creuse, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kyanite
Kyanite is a typically blue aluminosilicate mineral, found in aluminium-rich metamorphic pegmatites and sedimentary rock. It is the high pressure polymorph of andalusite and sillimanite, and the presence of kyanite in metamorphic rocks generally indicates metamorphism deep in the Earth's crust. Kyanite is also known as disthene or cyanite. Kyanite is strongly anisotropic, in that its hardness varies depending on its crystallographic direction. In kyanite, this anisotropism can be considered an identifying characteristic, along with its characteristic blue color. Its name comes from the same origin as that of the color cyan, being derived from the Ancient Greek word κύανος. This is generally rendered into English as ''kyanos'' or ''kuanos'' and means "dark blue". Kyanite is used as a raw material in the manufacture of ceramics and abrasives, and it is an important index mineral used by geologists to trace metamorphic zones.
