What is Lithium silicate aqueous solution?

What is a lithium silicate aqueous solution?
Lithium silicate aqueous solution is characterized by good chemical stability, high transparency, high viscosity, good water resistance and environmental friendliness, etc. It is widely used in the fields of construction, coating, adhesive, battery, glass ceramics, and chemical industry. With the progress of science and technology and the development of industrial production, the application fields of lithium silicate aqueous solution will continue to expand, and its role in various fields will be more prominent. Therefore, the in-depth study and application of lithium silicate aqueous solution has important practical significance and broad market prospects.
What is Lithium silicate?
Lithium silicate is a compound formed by the structure of lithium metal and silicate root, and its trade name is lithium water glass. Most lithium silicate is prepared by the lithium hydroxide method; that is, sodium silicate reacts with sulfuric acid to produce hydrated silicic acid and sodium sulfate and then takes hydrated silicic acid to react with lithium hydroxide to produce lithium silicate and water. Lithium silicate is an odorless, tasteless, transparent liquid with a pH value of about 11, alkaline, soluble in water and alkaline solutions, but insoluble in alcohols and organic solvents.
Lithium silicate has some unique characteristics, such as the ability to free gel with acid action and good self-drying properties. When the water in the solution evaporates, it can generate a dry film that is insoluble in water, and this water irreversibility makes the waterproof effect of lithium silicate particularly obvious.
The preparation method of lithium silicate
There are various methods for the preparation of lithium silicate, of which the more traditional is the solid-phase method. This method generally uses Li-OH-H2O, Li2CO3, and SiO2 as raw materials and lithium silicate powder is obtained by mixing ball milling and forging at high temperatures. Although the solid-phase method of preparing lithium silicate has the advantages of high powdering efficiency, low cost, and simple preparation, it also has the disadvantages of low efficiency, high energy consumption, and coarse powder particles.
Another method for preparing lithium silicate is the sol-gel method, which is a commonly used liquid phase method. This method allows the reactants to be uniformly mixed, the reaction temperature is low, and the reaction is easy to carry out. When preparing lithium silicate powder, choosing the right raw material is crucial.
Features of lithium silicate aqueous solution
Chemical stability: Lithium silicate aqueous solution has good chemical stability, and it is not easy to react with other substances. This makes the lithium silicate aqueous solution, in the storage and use process, able to maintain its stability for a longer period of time, reducing the performance changes caused by chemical reactions.
High transparency: Lithium silicate aqueous solutions are highly transparent, which is conducive to observing their changes during use. Increased transparency also allows lithium silicate aqueous solutions to better control the reaction process when preparing other materials.
High Viscosity: Lithium silicate aqueous solution has a high viscosity, which makes it uniquely advantageous in certain applications. For example, in coatings and adhesives, a high-viscosity lithium silicate aqueous solution can better adhere to the substrate, improving the product's adhesion and durability.
Good water resistance: Lithium silicate aqueous solution has good water resistance and maintains good performance even in humid environments. This makes lithium silicate aqueous solution has a wide range of application prospects in the fields of construction and coating.
Environmental protection: Lithium silicate aqueous solution is non-toxic and harmless and will not pollute the environment. At the same time, its production process is relatively simple and low energy-consuming, in line with environmental requirements.
