    Solid Sodium Silicate Modulus 3.1-3.3

    What is Solid Sodium Silicate?

     

    Solid sodium silicate, also known as solid water glass, is an inorganic silicate compound with the chemical general formula Na₂O·nSiO₂.

    It is produced by melting quartz sand (SiO₂) and soda ash (Na₂CO₃) at high temperature, then cooling and crushing into solid lumps, flakes or granules.

    Sanlee Chemical as a professional sodium silicate manufacturer and reliable sodium silicate solid supplier, we provide high-purity industrial sodium silicate with stable performance, especially the customized solid sodium silicate modulus 3.1-3.3 that meets diverse industrial production needs.

    The appearance of solid sodium silicate is transparent/translucent glassy solid, colorless, light gray or pale green; hard and brittle. It is not soluble in cold water, but slowly dissolves/hydrolyzes in hot water to form liquid sodium silicate solution (liquid water glass) 

     

    Introduction to Sodium Silicate Solid

     

    Solid sodium silicate, widely known as solid water glass, is a versatile inorganic silicate compound with the general chemical formula Na₂O·nSiO₂.

    It is industrially manufactured by fusing high-purity quartz sand and soda ash at extreme temperatures ranging from 1200℃ to 1400℃, followed by rapid cooling and crushing into hard, brittle, glassy solid lumps or flakes. This anhydrous solid product features adjustable modulus, referring to the variable ratio of silicon dioxide to sodium oxide, which directly dictates its physical and chemical performances for diverse industrial scenarios.

    Visually, it appears colorless, translucent or pale gray with stable solid-state properties, boasting longer shelf life and higher concentration compared to liquid sodium silicate. It is insoluble in cold water, ethanol and acidic solutions, but can gradually dissolve and hydrolyze in hot water to form homogeneous alkaline silicate solutions.

    Possessing excellent adhesion, heat resistance, acid resistance and fire-retardant properties, solid sodium silicate serves as a fundamental industrial chemical.

    It is extensively applied as a high-strength binder for foundry sand molds and refractory materials, a sealing and waterproof agent for concrete construction, and a key raw material for producing liquid water glass, ceramic glazes and industrial detergents. Its stable performance and cost-effectiveness make it an indispensable material in construction, metallurgy, chemical and environmental protection industries.

    Sanlee Chemical as a professional potassium water glass supplier, we provide high-purity industrial potassium silicate with stable performance, especially the customized solid potassium silicate modulus 3.3-3.9 that meets diverse industrial production needs.

    It is a core auxiliary material for many industries. This article will provide a detailed analysis of the basic properties, core characteristics, and multi-field applications of Potassium silicate glass, and helping everyone fully understand its application value, as well as the practical significance of potassium water glass in industrial and agricultural production.

     

    Basic Properties and Core Characteristics of Potassium silicate glass (Potassium water glass)

     

    Potassium silicate glass, as an inorganic compound, has a definite chemical composition and unique physical and chemical properties, which determine its wide range of applications. The specific details are as follows:

     

    (1) Basic Physical and Chemical Properties

     

    The chemical formula of Potassium silicate glass is usually written as K₂O·nSiO₂ (n is the modulus, representing the ratio of silicon dioxide to potassium oxide). Its appearance is mostly colorless or slightly yellowish transparent glass-like particles or blocks, with a hard texture and being difficult to break. Its core physical properties are outstanding. Its melting point is as high as 976℃, and it has excellent high-temperature resistance, not melting or deforming in high-temperature environments.

    In terms of chemical properties, it can quickly dissolve in water, forming an alkaline solution after dissolution, which can react with acids to produce silicic acid precipitates, but it does not dissolve in organic solvents such as ethanol, and its stability is extremely strong—this is one of the most prominent chemical characteristics of potassium water glass.

     

    (2) Core Feature Advantages

     

    Apart from its basic properties, the core characteristics of Potassium silicate glass make it suitable for various application fields:

    Firstly, it has strong adhesion, and the alkaline solution formed after dissolution has excellent adhesion ability, which can firmly bond various substances;

    Secondly, it has excellent heat resistance and fire resistance, with a high melting point and non-flammability, making it suitable for high-temperature scenarios and fire prevention requirements;

    Thirdly, it has good corrosion resistance, capable of resisting the erosion of various acids and alkalis, with strong stability; Fourthly, it is environmentally friendly and non-toxic, belonging to inorganic materials, without irritating odors, and relatively friendly to the environment and human body, suitable for various scenarios such as agriculture and civilian use.
