Effect of Sodium Silicates on the Properties of Iron

Silicate added before iron was oxide had a very large impact on reducing iron suspension turbidity (Figure 1) and color, and particle size. The following discussions will pertain to the case of pre-silicate addition. • Sodium silicate reduced the color and turbidity of iron

Sodium silicate Wikipedia

Sodium silicate is a generic name for chemical compounds with the formula Na 2x Si y O 2y+x or (Na 2 O) x · (SiO 2) y, such as sodium metasilicate Na 2 SiO 3, sodium orthosilicate Na 4 SiO 4, and sodium pyrosilicate Na 6 Si 2 O 7.The anions are often polymeric.These compounds are generally colorless transparent solids or white powders, and soluble in water in various amounts.

Interactions between Iron Oxides and Silicates

Soluble sodium silicates, also known as ‘water glass’, are probably one of the oldest and most widely used industrial chemicals [2]. Among a wide variety of applications, sodium silicate is used as a deflocculation agent in clay mining processes and ore flotation because of its surface charge modifying ability. In ore flotation, sodium

Optical spectroscopy of sodium silicate glasses prepared

The oxidation state of iron in the sodium silicate glasses was varied by changing the size of iron oxide particles used for preparation of glass batches and the melting temperature. In sodium silicate glasses iron commonly exists as an equilibrium mixture of ferrous ions, Fe2+, and ferric ions Fe 3+. The increase of the melting temperature led

An XPS study of iron sodium silicate glass surfaces

Dec 01, 1996· Iron sodium silicate glasses are mixed valence compounds in that they contain both oxidation states (Fe2+ and Fe3 +) and, as a result, have electrical and magnetic properties that are of particular technological importance [5-7]. In these glasses, the electronic conduction process is due to the hopping of a 3d electron from the Fez+ to the Fe3

Sodium Silicate Binders for Green Sand Metalcasting Foundry

The curing of a sodium silicate solution mixed with sand is the result of complex changes that contribute to the hardening of the core or mold. Usually theCO 2 flow rate is 1 5 % based on silicate. Use a dry CO 2 as water is detrimental to gassing speed and overall strengths. Phenolphthalein, at a level of 0.75 % based on sand, may be used as

Iron and boron removal from sodium silicate using

Silica purification of other materials is needed to improve the purity of silica that suitable for solar cells requirement. The silica is obtained from roasting of sand minerals in sodium silicate form. Iron (Fe) and boron (B) are an impurity that must be separated to obtain high pure silica. Separation of Fe and B used complexation methods.
