Detailed
What is Sodium Metasilicate Pentahydrate?
Sodium metasilicate pentahydrate is commonly known as instant water glass.
It is an inorganic salt product. Among the varieties of sodium metasilicate, the most widely used and most typical one is sodium metasilicate pentahydrate.
The molecular formula of its crystal is usually written as Na2SiO3·5H2O. It is actually a tetrahydrate of disodium dihydrogen orthosilicate with two cations. Its solubility (20℃) is 50Chemicalbookg/100g water, and its melting point is 72℃. Sodium metasilicate pentahydrate has the general characteristics of sodium silicate and sodium metasilicate, and has a certain binding capacity for calcium and magnesium ions, especially the binding capacity for magnesium ions is greater than 260mgMgCO2/g (35℃, 20min).
Core Features
It is a non-toxic, odorless, pollution-free white powder or crystalline granules,
easily soluble in water, insoluble in alcohol and acid, hygroscopic, the aqueous solution is alkaline,
and it is easy to absorb moisture and deliquesce in the air.
Sodium Metasilicate Pentahydrate
1. It has the properties of descaling, emulsification, dispersion, wetting, permeability and pH buffering.
It has strong decontamination ability.
2. It has large pH buffering capacity and can neutralize acidic dirt and emulsify fats and oils.
3. It has a deflocculation effect on inorganic substances.
4. It has an anti-corrosion effect on metals.

FAQ
What is advantages of Sodium Metasilicate Pentahydrate in Detergent Applications?
Sodium metasilicate is easy to mix with other commonly used diluents such as soda ash, phosphate, sodium humate, etc. to form a dilutable disintegrator, which has better disintegration performance than a single disintegrator.
Sodium metasilicate pentahydrate has a strong wetting, emulsifying and saponifying effect on fatty substances, has a strong degreasing performance, is widely used in the preparation of various detergents, and is the best substitute for sodium tripolyphosphate.
What is the difference between the uses of anhydrous sodium metasilicate and pentahydrate sodium metasilicate?
Anhydrous sodium metasilicate is an important inorganic chemical raw material, usually used in glass, cement, textile, printing and dyeing, papermaking and other industrial fields. Sodium metasilicate pentahydrate is more commonly used as building materials, chemical reagents, etc. In addition, anhydrous sodium metasilicate can also be used in preservatives and detergents, while sodium metasilicate pentahydrate can be used to prepare sodium aluminum silicate calcium cement, chemical analysis reactions, etc.
What is the role of sodium metasilicate pentahydrate in the ceramic industry
The reason why sodium metasilicate has a diluting effect is that it can increase the surface charge density of the micelles in the mud,
Thereby increasing the double electric layer and zeta potential, and increasing the repulsive force between particles;
At the same time, the silicate anions contained in sodium metasilicate can form insoluble substances with the harmful ions Ca2+ and Mg2+ in the mud, promote the exchange of Na+, reduce the viscosity of the mud, and increase the fluidity. It is particularly suitable as a ceramic mud grouting forming additive.
