Brazilianite begins to lose its color when heated to 200 �C and becomes colorless when it is heated to 300 �C.
12.
Some of the oxygen atoms in the four OH groups in brazilianite act as donors and some as acceptors of the hydrogen bond.
13.
Brazilianite is typically found in granite pegmatite and it is often found the cavities within the pegmatite where quartz, beryl and mica are also found.
14.
Brazilianite is a mineral in the monoclinic system that is part of the point group 2 / m and belongs to the space group P21 / n.
15.
Brazilianite, NaAl 3 ( PO 4 ) 2 ( OH ) 4 is a hydrous sodium aluminium phosphate that forms through the metasomantic alteration of amblygonite-montebrasite.
16.
Brazilianite is composed of chains of edge-sharing Al-O octahedra that are linked by P-O tetrahedra with sodium in the cavity of the framework.
17.
During the hydrothermal stage, the pegmatite containing the brazilianite is traversed by a late stage low temperature hydrothermal veins where amblygonite-montebrasite is altered to form brazilianite.
18.
During the hydrothermal stage, the pegmatite containing the brazilianite is traversed by a late stage low temperature hydrothermal veins where amblygonite-montebrasite is altered to form brazilianite.
19.
Messelite occurs in association with amblygonite, anapaite, brazilianite, eosphorite, fair�eldite, goyazite, graftonite, herderite, hureaulite, ludlamite, phosphoferrite, siderite, triphylite, vivianite, and whitlockite.
20.
Amblygonite, LiAlPO 4 F in combination with quartz goes through an OH-F exchange to make montebrasite, LiAlPO 4 { F, OH } at temperatures greater than 480 �C . Due to its formation caused by the amblygonite-montebrasite alteration and the presence of tourmaline in the environment where brazilianite forms, different elements are present in the mineral such as P, Al, Fe, Mn, Ba, Sr, Ca, Mg, Na, K, F, and Cl.
