tiivistelesilikat

Tiivistelesilikat, often translated as soluble silicates or water glass, are a class of inorganic compounds formed by dissolving silica (silicon dioxide) in an alkali metal hydroxide solution, typically sodium hydroxide or potassium hydroxide. The resulting solution is viscous and contains silicate anions with varying degrees of polymerization. These compounds are generally colorless, odorless, and alkaline in nature.

The properties of tiivistelesilikat depend on the ratio of alkali oxide to silicon dioxide (molar ratio) and the concentration of the solution. Higher molar ratios result in more soluble and less viscous solutions, while lower ratios lead to more viscous solutions with a greater tendency to gel.

Tiivistelesilikat find widespread applications across various industries. They are used as binders in detergents, where they help to stabilize the formulation and enhance cleaning performance. In construction, they act as concrete hardeners and waterproofing agents, penetrating the pores of concrete to form a durable, water-repellent surface. The paper industry utilizes them as sizing agents to improve paper strength and printability, and also in the de-inking process of recycled paper. Furthermore, they serve as adhesives for cardboard and paper products, fire-resistant coatings, and as precursors for the production of silica gels and precipitated silica, which have their own extensive uses. Their versatility stems from their ability to form gels, bind particles, and react with other materials.
