What is Na3AlF6?
cryolite, colourless to white halide mineral, sodium aluminum fluoride (Na3AlF6).
What type of salt is cryolite?
Cryolite is a salt of sodium aluminium hexafluoride. It is represented as Na3AlF6. It consists of Aluminium, Sodium and Fluorine.
What is cryolite?
Definition of cryolite : a mineral consisting of a fluoride of sodium and aluminum found especially in Greenland usually in white cleavable masses and formerly used as a source of aluminum.
What is the formula and function of cryolite?
The formula of cryolite is Na 3 AlF 6 . Cryolite is added to the molten mixture of alumina to reduce the melting point. Pure cryolite melts at 1012 °C (1285 K), and it can dissolve the aluminium oxides sufficiently For the easiness of extraction of the aluminium by electrolysis.
What is the formula for halite?
This is the common name for the mineral “halite”. Its chemical formula is NaCl.
What is the molar mass of Na3AlF6?
209.94 g/molSodium hexafluoroaluminate / Molar mass
Is cryolite an ionic compound?
To reduce costs, powdered aluminium oxide is dissolved in molten cryolite. This ionic compound melts at a lower temperature than aluminium oxide, reducing costs. However, significant amounts of energy are required to melt the cryolite.
What type of resource is cryolite?
Answer: Cryolite (Na3AlF6, sodium hexafluoroaluminate) is an uncommon mineral identified with the once-large deposit at Ivittuut on the west coast of Greenland, depleted by 1987. Due to its rarity it is possibly the only mineral on Earth ever to be mined to commercial extinction.
What is the trade name of cryolite?
DESCRIPTION OF CHEMICAL Generic name: Sodium aluminofluoride or (Chemical) sodium fluoaluminate Common name: Cryolite Trade Names: Kryocide and Prokil Other Chemical Nomenclature: trisodium hexafluoroaluminate, sodium hexafluoroaluminate, and sodium aluminum fluoride EPA Pesticide Chemical (Shaughnessy) Number: 075101 …
What is cryolite Class 10 geography?
Cryolite is sodium hexafluroaluminate (Na3AlF6). When aluminum is extracted from its ore bauxite (it is an oxide ore), there is difficulty in separating aluminum from oxygen.So, cryolite is used as a flux which dissolves the mineral ores which increases the ease of extraction of aluminum by electrolysis.
What is Gypsum formula?
Gypsum is the name given to a mineral categorized as calcium sulfate mineral, and its chemical formula is calcium sulfate dihydrate, CaSO4⋅ 2H2O.
What is the molar mass of NaCl?
Molar mass of NaCl = 58.44277 g/mol This compound is also known as Sodium Chloride. Convert grams NaCl to moles or moles NaCl to grams
What is the density of cryolite?
Density: 2.95 g/cm3. Dust irritates the eyes and skin; inhaled dust irritates the nose, mouth and lungs. Insoluble in water. Synthesized by fusion of sodium fluoride and aluminum fluoride as a electrolyte in the reduction of alumina to aluminum metal. Occurs in nature as the mineral cryolite.
How is cryolite obtained from natural mineral?
Cryolite may be obtained by (a) mining natural mineral cryolite or (b) synthesis by the reaction of aluminum oxide, sodium chloride and hydrogen fluoride. Sittig, M. (ed.) Pesticide Manufacturing and Toxic Materials Control Encyclopedia. Park Ridge, NJ: Noyes Data Corporation. 1980., p. 218
What is aluminium cryolite?
Synthesized by fusion of sodium fluoride and aluminum fluoride as a electrolyte in the reduction of alumina to aluminum metal. Occurs in nature as the mineral cryolite.
