The method of producing aluminum from nepheline

The purpose of the invention is to simplify the process of obtaining aluminum from nepheline and sennariolo raw materials. The inventive process is carried out by one-step processing of this raw material mixture of fluorine and chlorine at a temperature 870-1200 o C to obtain a reaction mixture consisting of immiscible between a fluoride-silicate and chloride-aluminum alkaline melts.

Crystallisation and microstructure of nepheline–forsterite

2013/4/1This work presents the results of a study focused on the development of forsterite–nepheline glass-ceramic with the use of rice husk ash (RHA) as a silica source. The glass-ceramics were produced by a sintering process of a glassy frit formulated in the MgO–Al 2 O 3 –SiO 2 base system with the addition of B 2 O 3 and Na 2 O to facilitate the melting and pouring processes.

Fineton Development Limited

Nepheline Syenite enables the glass batches to have lower viscosity and easier workability compared with Potash Feldspar. That makes it very suitable for the glass making industry. In the glass batch, alumina acts as a matrix of stabilizer, enhancing the workability of molten glass, and increasing the resistance for scratching, breaking and chemical protection. Get price
