Calcium metasilicate is widely used in various industries due to its versatile properties. In the construction industry, it serves as a key component in cement and concrete formulations, enhancing durability, strength, and resistance to corrosion. It is also employed in the production of ceramics, tiles, pottery, and glass, where it acts as a flux to lower melting temperatures and improve material properties such as strength and durability. In the manufacturing of paints and coatings, it serves as a filler and extender, improving texture, opacity, durability, and uniformity. Additionally, it is utilized in the production of insulation materials due to its thermal resistance properties. In the agricultural sector, it is applied as a soil conditioner to improve soil structure and nutrient availability. In the paper industry, it is used as a production aid to enhance paper quality and increase brightness and opacity. Its non-toxic nature makes it suitable for use in food and pharmaceutical industries as an anti-caking agent and excipient.
