On silicic acid
Silicic acid, it has its own unique properties in all kinds of things, and has a wide range of functions. The preparation method is also important for Fang family.
First, the properties of silicic acid
Silicic acid, the texture is either gel-like or powder state. Its chemical properties are stable, and it is not easy to chemically react with common substances at room temperature. However, when encountering strong alkali, it can combine with it to form silicates. Its solubility is very different. In water, the solubility is quite low, and it is mostly in the form of precipitation or colloid.
Second, the application of silicic acid
Silicic acid is useful in both daily and industrial fields. In daily use, many desiccants are often made of silica acid. Because of its good water absorption, it can keep the environment dry and prevent items from being damp and mildew. In industry, silica acid is an indispensable raw material for the art of glass manufacturing. Its participation in the glass forming process can make the glass better transparency and hardness, and can adjust the melting point and expansion coefficient of the glass. Ceramic production also relies on silica acid. Adding silica acid can improve the properties of the ceramic body, make the ceramic product dense in texture, warm in color, and enhance its heat resistance and wear resistance.
Third, the preparation of silica acid
There are several common methods for preparing silica acid. First, the soluble silicate and acid phase are used. If sodium silicate solution is mixed with hydrochloric acid, a metathesis reaction occurs, that is, silicic acid is formed. This reaction is easy to control and the conditions are mild. This method is often used to prepare silicic acid in the laboratory. However, the obtained silicic acid is initially in a colloidal state and requires subsequent treatment to obtain pure silicic acid. Second, it is prepared under special conditions of chemical reaction. For example, under specific temperatures, pressures and catalysts, silicon-containing substances are converted into silicic acid through complex reactions. Although the process is complicated, high-quality silicic acid products can be obtained in large-scale industrial production. Silicic acid, with its unique properties, wide application, and diverse preparation methods, occupies an important position in the forest of materials, providing a solid foundation for the development of many fields.
