Product Description
Silicon Dioxide (SiO₂), commonly known as silica, is a high-purity, white, odorless, and chemically inert compound composed of silicon and oxygen. It occurs naturally as quartz and is widely used in laboratory, pharmaceutical, food, and industrial applications due to its stability, high melting point, and adsorptive properties.
In laboratories, Silicon Dioxide serves as a stationary phase in chromatography, a drying agent, and a support medium for catalysts. In industrial and pharmaceutical applications, it functions as an anti-caking agent, thickener, and excipient, ensuring product stability and uniformity.
