Abstract. Spent pot lining (SPL) is a carbon rich material generated during primary aluminium smelting process. The major constituents of SPL are carbon (40–50%), fluoride (10–18%), aluminium (10–13%), cyanide (700–4500 ppm) and sodium (12–16%) along with other metals like calcium, iron, lithium, titanium and magnesium in trace amounts.

AISI 304 Stainless Steel (UNS S30400, SS 304) AISI 304 stainless steel (UNS S30400) is the most widely used stainless steel, containing 18-20% Cr and 8-10.5% Ni, and also known as 18-8 stainless steel.SS 304 is non-magnetic under annealing conditions, but after cold working (such as stamping, stretching, bending, rolling), part of the austenite structure may be converted into martensite and ...


The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.

The mineral cryolite is a double fluoride of sodium and aluminum and has a stoichiometric composition very close to the formula Na 3 AlF 6 and a melting point of about 1011°C. It has been found in substantial quantities only in Greenland. Cryolite was mined extensively there in the early twentieth century, but the mine is now essentially ...


The Hall–Héroult process is a major industrial process that involves the smelting of aluminium. It involves dissolving aluminium oxide (alumina) obtained from bauxite through Baeyer's process. In this process, pure alumina is mixed with Calcium fluoride ( C a F 2) or Cryolite ( N a 3 A l …

There is general agreement that molten cryolite is completely ionised to sodium ions and hexafluoroaluminate ions: [3.6] N a 3 Al F 6 = 3 N a + + Al F 6 3 −. Also it is well established that the hexafluoroaluminate anion dissociates further: [3.7] Al F 6 3 − = Al F 4 − + 2 F −. At the cryolite composition the anion is about 30% dissociated.


Cryolite is a suitable host for up-conversion luminescent materials due to its low phonon energy and good optical transparency. In this work, a novel up-conversion material K 3 YF 6:Yb 3+, Er 3+ with a cryolite structure was prepared successfully by a solid state method. The crystal structure, morphology, composition and up-conversion luminescence properties of the as-prepared sample were ...
