Aluminium (III) phosphate, is an inorganic salt uncovered in part minerals and used through the chemical together catalyst and also by the pharmaceutical sector to achieve chemotherapeutics drugs.

You are watching: What is the formula for aluminum phosphate?

Formula and structure: The aluminium phosphate chemical formula is AlPO4 and its molar mass is 121.9529 g mol-1. Aluminium phosphate greatly exists in nature as the anhydrous salt AlPO4. The dihydrate and also pentahydrate forms additionally exist in nature: AlPO4.2H2O and also AlPO4.5H2O. The molecule is developed by the phosphate one anion PO43- and the aluminium cation Al3+. The anhydrous salt framework is very similar to various other minerals together quartz, through an trigonal decision system, however the dihydrate kind is comparable to NaCl structure and 6 cations coordinated to 6 anions and also viceversa. Its chemistry structure deserve to be composed as below, in the typical representations used for necessary molecules.


Occurrence: Aluminium phosphate is discovered in nature, similarly to other aluminium salt, is a mineral: the berlinite. The dihydrate type is uncovered in the minerals: variscite and meta-variscite. The significant reserves of this minerals room in Australia and also Southern Africa.

Preparation: Aluminium phosphate is extracted from the minerals berlinite, variscite and meta-variscite. Chemical approaches to prepare it are not really extended or related in literature.

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

Chemical properties: Aluminium phosphate walk not have only the structure of quartz SiO4, that has additionally the chemistry properties of it. Aluminium phosphate presents piezoelectric properties. Moreover, aluminium phosphate exhibits chirality, one characteristic really common in essential compound however so rarely in inorganic salts.

Uses: Aluminium phosphate is supplies in electrical and electronic industries due its properties together piezoelectric material. It is likewise used in the manufacturing of rubbers and also adhesive. Aluminium phosphate is a ingredient of the many used antiacids.
