Sodium Aluminate for Titanium Dioxide

A: In construction technology, sodium aluminate is used to accelerate the solidification of concrete, mainly when working during freezing. Sodium aluminate is also used in the paper industry, for the production of refractory bricks, the production of alumina, etc.

A: The surface treatment of TiO 2 particles with oxide coating is a major processing step in titanium dioxide pigment production. It is a delicate and complex process where reaction conditions such as pH, ionic concentration, and temperature, have to be carefully monitored and adjusted.

A: Titanium dioxide is insoluble in water, hydrochloric acid, dilute sulfuric acid, and organic solvents. It dissolves slowly in hydrofluoric acid and hot concentrated sulfuric acid.

A: Contacting a titanium dioxide-containing material located on a non-titanium surface with an alkaline aqueous composition comprising water, an alkali component and a metal chelating agent other than gluconate.

A: AluSAL 38% is a popular solution for multiple water treatment applications, with excellent phosphorus control properties. AluSAL is a solution of Na2Al2O4 with a Na2O/Al2O3 Mole Ratio of typically 1.51.

A: These materials are insoluble sodium aluminosilicates, which act by exchanging their sodium with calcium ions. They are safe and inexpensive materials, but they suffer from several drawbacks: they bind calcium only, their binding action is quite slow, and they can form visible deposits on fabrics.

A: An electrochemical method for the direct reduction of solid TiO2 was introduced, in which the oxygen is ionized, dissolved in the molten salt and discharged at the anode, leaving pure titanium at the cathode.

A: Multi-purpose application: due to its properties, Sodium Aluminate is a universal product and it is widely used as a raw material in production, as well as a coagulant for water treatment.
