Cryolite is a sodium aluminum fluoride mineral. It is a white glassy stone with a similar refractive index as water and disappears when submerged, but it does not dissolve. This property of cryolite is also the reason it is called 'ice-stone.'. It is a birthstone for the people in the Aquarius and Gemini zodiac sign.

Cryolite An interesting feature of this mineral is that it "disappears" when immersed in water due to the similarity in refractive indices. It is named from two Greek words meaning "frost" and "stone", in allusion to its frosty appearance.

Abstract. Cryolite, Na 3 [AlF 6 ], is essential to commercial aluminium production because alumina is readily soluble in molten cryolite. While the liquid state has been extensively investigated, the spectroscopy of the solid state has been largely ignored. In this paper, we show that the structure at 5 K is the same as that at room temperature.

Aluminium is produced by electrolysis using alumina (Al 2 O 3) as raw material and cryolite (Na 3 AlF 6) as electrolyte. In this Hall–Héroult process, the energy consumption is relatively large, and solid wastes such as spent anodes and spent pot liner, flue gas and waste heat are generated. Therefore, this article discusses from the ...

Aluminum (Al) Ore. Aluminum ore, also known as bauxite, is a naturally occurring mineral rock that contains aluminum in the form of aluminum oxide (Al2O3) mixed with various impurities. Bauxite is the primary source of aluminum, which is one of the most abundant elements in the Earth's crust, comprising about 8% by weight.

Cryolite, or sodium aluminum fluoride (Na3AlF6), consists of 12.85 percent aluminum, 54.30 percent fluorine, and 32.85 percent sodium. It crystallizes in the monoclinic system, but occurs primarily in massive form. With a Mohs hardness of 2.5 and a specific gravity of 2.98, cryolite is much softer and a bit denser than quartz.
