Aluminium phosphate is a chemical compound. In nature it occurs as the mineral berlinite. [3] 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. [4] Commercial aluminium phosphate gel is available.
Wavellite is an aluminium basic phosphate mineral with formula Al 3 (P O 4) 2 (OH, F) 3 ·5H 2 O. Distinct crystals are rare, and it normally occurs as translucent green radial or spherical clusters. Distinct crystals are rare, and it normally occurs as translucent green radial or spherical clusters.
Aluminium phosphide is a highly toxic inorganic compound with the chemical formula AlP, used as a wide band gap semiconductor and a fumigant. This colorless solid is generally sold as a grey-green-yellow powder due to the presence of impurities arising from hydrolysis and oxidation .
Aluminium phosphide has a fatal dose of between 0.15 and 0.5 grams (0.0053 and 0.0176 oz). [14] The mortality rates from AAlPP vary from 35 to 85 percent. [15] The actual numbers of cases may be much larger, as less than five percent of those with AAlPP eventually reach a tertiary care center. [10]
Berlinite (aluminium phosphate, chemical formula AlPO 4 or Al(PO 4)) is a rare high-temperature hydrothermal or metasomatic phosphate mineral. [5] 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. [3]
Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% [1] to 20% phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more ...
The aluminium salt, when ingested, binds to phosphate in the intestines and reduce the amount of phosphorus that can be absorbed. [27] [28] Precipitated aluminium hydroxide is included as an adjuvant in some vaccines (e.g. anthrax vaccine). One of the well-known brands of aluminium hydroxide adjuvant is Alhydrogel, made by Brenntag Biosector.
Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
