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.
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]
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
Variscite is a secondary mineral formed by direct deposition from phosphate-bearing water which has reacted with aluminium-rich rocks in a near-surface environment. [6] It occurs as fine-grained masses in nodules, cavity fillings, and crusts. Variscite often contains white veins of the calcium aluminium phosphate mineral crandallite.
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.
Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminium oxide hydroxide, AlO(OH), and aluminium oxide or alumina (Al 2 O 3), the latter of which is also amphoteric. These compounds together are the major components of the aluminium ore bauxite. Aluminium hydroxide also forms a gelatinous ...
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.
Augelite is an aluminium phosphate mineral with formula: Al 2 (P O 4)(OH) 3.The shade varies from colorless to white, yellow or rose. Its crystal system is monoclinic. [4]It was first described by Christian Wilhelm Blomstrand for an occurrence in Västanå iron mine at Scania, Sweden in 1868 and derives its name from the Greek αύγή in reference to its pearly lustre.
