Aluminium (III) phosphate, is an not natural salt found in part minerals and also used by the chemical as catalyst and also by the pharmaceutical sector to attain chemotherapeutics drugs.

You are watching: What is the formula for aluminum phosphate

Formula and also structure: The aluminium phosphate chemical formula is AlPO4 and also its molar massive is 121.9529 g mol-1. Aluminium phosphate mostly exists in nature together the anhydrous salt AlPO4. The dihydrate and also pentahydrate forms additionally exist in nature: AlPO4.2H2O and AlPO4.5H2O. The molecule is created by the phosphate an anion PO43- and the aluminium cation Al3+. The anhydrous salt framework is very similar to various other minerals together quartz, with an trigonal decision system, but the dihydrate type is similar to NaCl structure and 6 cations coordinated to 6 anions and also viceversa. Its chemistry structure have the right to be written as below, in the typical representations used for essential molecules.


Occurrence: Aluminium phosphate is uncovered in nature, similarly to various other aluminium salt, is a mineral: the berlinite. The dihydrate kind is found in the minerals: variscite and meta-variscite. The major reserves of these minerals space in Australia and also Southern Africa.

Preparation: Aluminium phosphate is extracted from the minerals berlinite, variscite and also meta-variscite. Chemical methods to prepare it space not very extended or associated in literature.

Physical properties: Aluminium phosphate is an odorless, white crystalline powder. Its density is 2.567 g mL-1. The melting point is 1800 ºC and above this temperature, aluminium phosphate decomposes. That is insoluble in water but slightly dissolve in hydrochloric acid and nitric acid.

Chemical properties: Aluminium phosphate walk not have only the framework of quartz SiO4, it has also the chemical properties of it. Aluminium phosphate presents piezoelectric properties. Moreover, aluminium phosphate exhibits chirality, an characteristic really common in necessary compound yet so rarely in inorganic salts.

Uses: Aluminium phosphate is provides in electrical and also electronic sectors due the properties together piezoelectric material. That is additionally used in the manufacturing of rubbers and adhesive. Aluminium phosphate is a component of the most used antiacids.
