Difference Between Sodium Silicate and Sodium Metasilicate

Thekey difference在硅酸钠和钠钠之间是the term sodium silicate refers to silicate salts ofsodiumions whereas sodium metasilicate is a type of sodium silicate having a sodium cation and SiO₃^2-anion。

Sodium silicate is a generic name (common name for all ionic compounds having the general chemical formula Na_2xSi_yO_2y+x). Therefore, sodium metasilicate is a type of sodium silicate.

What is Sodium Silicate?

Sodium silicate is a common name for allionic compoundshaving the general chemical formula Na_2xSi_yO_2y+x。The most common members of this group include sodium metasilicate, sodium orthosilicate and sodium pyrosilicate. Often, the anions in these sodium silicates are polymeric substances. Generally, sodium silicates are colorless, transparent solid compounds that are available as either solids or white powder form that is soluble in water (except for most silicon-rich silicates). When dissolved in water, sodium silicates form aqueous alkaline solutions.

硅酸钠在中性和碱性溶液中稳定。当它们处于酸性溶液中时，硅酸盐离子倾向于与氢离子反应，形成硅酸。这些硅酸成分倾向于分解为水合二氧化硅凝胶。当这种水合化合物被加热以驱除水时，它会产生一种坚硬的半透明物质，我们将其称为silica gel(a common desiccant).

There are several methods to produce sodium silicates, depending on the type of silicate. Typically, a sodium silicate is produced by treating a mixture of silica, caustic soda, and water in the presence of hot steam. In addition, we can get a sodium silicate via dissolving silica in molten sodium carbonate.

There are many applications of sodium silicate: as ingredients in detergents, paper, water treatment, construction materials, as drilling fluid in bore walls, in metal repairing, automotive repairing, etc.

什么是钠的硅酸盐？

Sodium metasilicate is an inorganic compound having the chemical formula Na₂SiO₃。它是市售硅酸钠溶液中的主要成分。这是一种含有钠阳离子和聚合物交流阴离子的离子化合物。这种离子化合物是一种无色，结晶和吸湿性固体，具有高度偏差。它可溶于水，但不溶于酒精。

When considering the production of sodium metasilicate, we can produce it by fusing silicon dioxide with sodium oxide in 1:1 molar ratio. Moreover, sodium silicate crystallizes from various hydrate solutions such as pentahydrate and nonahydrate.

有许多metasilica钠的重要用途te including the production of silica via the reaction between sodium metasilicate and acids, production of cement and binders, pulp, paper, soap, detergent, automotive applications, egg preservative, crafts, etc.

What is the Difference Between Sodium Silicate and Sodium Metasilicate?

Sodium metasilicate is a type of sodium silicate. The key difference between sodium silicate and sodium metasilicate is that sodium silicate refers to different ionic compounds which are silicate salts of sodium ions whereas sodium metasilicate is a type of sodium silicate having a sodium cation and SiO₃^2-anion.

Below infographic summarizes the difference between sodium silicate and sodium metasilicate.

概括– Sodium Silicate vs Sodium Metasilicate
