Specification

Nano silicon dioxide, also known as Fumed Silica Powder, is a type of silica that is produced in a highly pure and fine

powder form. It is primarily composed of silicon dioxide (SiO2) and is known for its high surface area and unique

properties.

Fumed Silica powder is made by burning silicon tetrachloride (SiCl4) in a flame of hydrogen and oxygen. The resulting

silicon dioxide particles are then collected and processed to form a fine powder. The particles have a diameter in the

nanometer range, typically ranging from 5 to 50 nanometers.

Due to its high surface area, fumed silica powder has excellent properties such as high absorbency, low density, and

high dispersibility. It is commonly used as a reinforcing filler in various materials, including rubber, plastics, adhesives,

and coatings. It can improve the mechanical properties, such as tensile strength and tear resistance, of these materials.

Fumed silica powder also has excellent thixotropic properties, meaning it can act as a thickening and anti-settling agent

in liquid systems. It can improve the viscosity and stability of paints, inks, and other liquid formulations.

Additionally, fumed silica powder is used as a flow aid and anti-caking agent in powdered products, such as

pharmaceuticals, cosmetics, and food. It can prevent clumping and improve the flowability of these powders.

In summary, nano silicon dioxide or fumed silica powder is a versatile material with a wide range of applications. Its high

surface area and unique properties make it valuable in various industries, including rubber, plastics, coatings, and

pharmaceuticals.
