Uses of silica
Silicon Dioxide (SiO2), commonly known as silica, is mostly found in the form of sand. Crystalline silica, a rock ore, is used across a wide range of industries.
The primary characteristic of silica, which adds value to its various applications, is the fact that it is chemically inert; in other words, it is not prone to chemical reaction with other reagents. The physical characteristics, such as its high melting point and particle shape, determine the purpose for which in can be applied. The particle shape is determined by the way the silica granules were formed and are processed. The subsequent mining and processing are the final and critical stages, where the quartzite or sand is converted into a usable form.
