Chemical Formula

What is sodium silicate? Sodium silicate, commonly known as effervescent alkali, is an inorganic substance, and its aqueous solution is commonly known as water glass.Its chemical formula is Na2O⋅nSiO2.

As a widely used industrial raw material, industrial sodium silicate possesses unique physical and chemical properties, such as excellent adhesion, high-temperature resistance, alkaline stability, and corrosion resistance, making it a fundamental material for industries including construction, manufacturing, chemical processing, and metallurgy.

Modulus N

In the chemical formula Na2·nSiO2, n represents the ratio of the moles of silicon dioxide to those of alkali metal oxides, and is called the modulus of sodium silicate.

This is a key indicator for differentiating various grades of water glass. This modulus directly determines the viscosity, solubility, curing speed and chemical stability of sodium silicate products.

Physical Forms

Sodium silicate exists in various physical forms, mainly including solid sodium silicate, liquid sodium silicate, and highly efficient instant soluble sodium silicate or called sodium silicate powder.

Solid sodium silicate appears as a light blue blocky solid, looking like a piece of blue glass.

The appearance of liquid sodium silicate varies depending on the content of impurities. When there are more impurities, it appears as a gray or light yellow transparent liquid. However, the higher-quality liquid sodium silicate has a clear and transparent appearance, similar to water.

Powdered sodium silicate presents as a white powder and is extremely soluble in water. After dissolving in water, it shows different aqueous solution appearances based on the content of impurities.

Each form has been customized for specific industrial scenarios. As an economical and environmentally friendly industrial chemical, industrial sodium silicate has replaced many traditional chemical additives and has become an indispensable raw material in modern industrial production.

Sanlee Chemical is a reputable producer of sodium silicate. It strictly classifies its products according to industry standards and provides customized sodium silicate solutions for different industrial needs.

Sodium silicate is mainly divided into the following three mainstream types: solid sodium silicate, liquid sodium silicate and instant soluble sodium silicate.

Each type of industrial sodium silicate has its own unique performance advantages and targeted application scenarios.

The following details the characteristics, specifications, and application fields of various core sodium silicate products.

Solid Sodium Silicate

Solid sodium silicate is the crystalline form of water glass.
It is produced by melting, cooling and solidifying the sodium silicate raw material at high temperatures. It usually appears as colorless or light blue transparent blocks, sheets or granular solids, with high hardness and stable chemical properties at room temperature.
Compared with liquid sodium silicate, solid sodium silicate has a longer storage period, lower transportation cost, and is less likely to leak or deteriorate during long-distance transportation. Therefore, it is suitable for long-term storage and large-scale transportation across regions.

Before use, the solid industrial-grade sodium silicate needs to be dissolved in hot water to prepare a liquid silica glass with the desired concentration and modulus.
Sanlee Chemical can produce solid sodium silicate products with customized particle size and modulus specifications according to customer requirements. The modulus of solid sodium silicate usually remains stable within the range of 2.0 to 3.4, and it has a high silicon content, excellent bonding strength and high-temperature resistance.
Solid sodium silicate has a strong hygroscopicity. During storage, it should be placed in a dry and well-ventilated environment to avoid deliquescence due to moisture absorption, as this phenomenon will affect the dissolution effect and performance.
By following the standardized packaging and storage guidelines provided by the reputable sodium silicate supplier enterprises, customers can effectively ensure the stability of the performance of solid silica glass.
