aluminum phosphate minerals

Aluminum phosphate–sulfate APS minerals occur as disseminated crystals in a wide range of geological environments near the Earth’s surface including weathering sedimentary diagenetic hydrothermal metamorphic and also postmagmatic systems

Aluminum Salts Aluminum hydroxide aluminum phosphate and potassium aluminum sulfate alum are used as adjuvants in vaccines designed to stimulate systemic immunity Aluminum salts are used in DPT pneumocccal conjugate hepatitis A papilloma anthrax and rabies vaccines

In reality the existence of 49 known calcium phosphates 14 magnesium phosphates 49 aluminum phosphates and 51 iron phosphates and some contain one or more of these cations points to the complexity of the chemistry of phosphate minerals in soils and it is dubious that any fertilizer reaction species or series is more than illustrative

Many cave phosphate minerals include the ammonium ion eg biphosphammite H 2 NH 4PO 4 struvite NH 4MgPO 4·6H 2 O taranakite etc which is derived from decomposition of bat urea After leaching of alkali ions the more stable minerals eg hydroxylapatite or brushite persist

Aluminum Ores These minerals are simultaneously used as a source of phosphates Other minerals which can be used as a source of aluminum include alunites leucitic lavas the mineral leucite labradorites anorthosites and highalumina clays and kaolins as well as cyanitic sillimanitic and andalusitic schists

Phosphate minerals Phosphate minerals are those minerals that contain the tetrahedrally coordinated phosphate PO 43− anion along with the freely substituting arsenate AsO 43− and vanadate VO 43− Chlorine Cl − fluorine F − and hydroxide OH − anions that also fit into the crystal structure The phosphate class

Variscite is a rare hydrated aluminum phosphate mineral with a chemical composition of AlPO 4 •2H 2 O It is usually green in color ranging from yellowish green to bluish green It is usually green in color ranging from yellowish green to bluish green

Aluminium hydroxide AlOH3 is found in nature as the mineral gibbsite and its three much rarer polymorphs bayerite doyleite and nordstrandite Aluminium hydroxide is amphoteric in nature ie it has both basic and acidic properties Closely related are aluminium oxide hydroxide AlO and aluminium oxide or alumina the latter of which is also amphoteric These compounds together are the major

Variscite is a hydrated aluminium phosphate mineral It is a relatively rare phosphate mineral It is sometimes confused with turquoise however variscite is usually greener in color The green color results from the presence of small amounts of chromium

Aluminium III phosphate is an inorganic salt found in some minerals and used by the chemical as catalyst and by the pharmaceutical industry to obtain chemotherapeutics drugs Formula and structure The aluminium phosphate chemical formula is AlPO 4 and its molar mass is 1219529 g mol 1

Amblygonite is a relatively common phosphate mineral It is found in lithium and phosphate rich pegmatites as a primary mineral At times it makes up a significant percentage of the rock although this fact may be overlooked Amblygonite as it turns out is easily confused for other host rock members such as quartz and albite

Disclosed are foundry binder compositions comprising boronated aluminum phosphate and water cured by contacting them with gaseous ammonia or an amine Optionally the composition may also include alkaline earth metals and oxides and solid polyhydric alcohols or solid organic carboxylic acids

Berlinite is a rare phosphate mineral first discovered at the Vestana iron mine Nastum Sweden It would not be very outstanding except for the fact that it is the only known mineral to be isostructural with quartz Isostructural means that they have the same structure although

Hydrated Copper Aluminum Phosphate Gemstones Minerals Turquoise Turquoise is a hydrated phosphate of copper and aluminum in the Phosphates Arsenates Vanadates group with a triclinic crystal system It rarely occurs as prismatic crystals It is usually found as lightblue or green masses nodules and veins

Amblygonite is a relatively common phosphate mineral It is found in lithium and phosphate rich pegmatites as a primary mineral At times it makes up a significant percentage of the rock although this fact may be overlooked Amblygonite as it turns out is easily confused for other host rock members such as quartz and albite
