In Zeosilichem Company, we invented a new method to produce nano silica in chemical industries to reduce the cost of energy and equipment, cost of the product, and environmental damages. Precipitated silica or nano-structured of silica (nano silica) is a synthetic silica that, due to its unique properties such as high specific surface area, high porosity, and chemical stability, is widely used in various industries including rubber and tires, paints and coatings, catalysts, toothpaste, cement and concrete, and adhesives. The production of precipitated silica is of particular importance due to its significance in various industries as well as its high potential for job creation, value addition, and reducing dependence on imports. This mineral is considered a strategic raw material and the development of its production industry can contribute to strengthening the national economy and increasing the competitiveness of various industries.
