Silicic acid is widely used across various industries and research due to its diverse properties.

In agriculture, it serves as a soil amendment to improve plant growth and resilience. It strengthens cell walls, enhancing resistance to pests and diseases, improves nutrient absorption, and helps plants tolerate environmental stresses like drought and heavy metals.

In the food industry, silicic acid is used as an additive to improve texture and stability in products such as bakery items and certain beverages.

In the medical and cosmetic sectors, it plays a key role in skincare products for its ability to retain moisture, stimulate collagen and elastin synthesis, and improve skin elasticity. It is also under study for applications in biomaterials for tissue repair and healing.

In the materials industry, silicic acid is employed in the production of glass, ceramics, and surface coatings to enhance durability and stability.

Additionally, it is utilized in water treatment processes to remove impurities and stabilize water quality. It also finds applications in the production of silica gels, which are used as desiccants and in chromatography for separation processes.
