Amorphous silica is a concept that is oftentimes used in scientific circles, but it has various synonyms that might make it easier to understand. For starters, amorphous silica is also known as non-crystalline silica or silica glass. This refers to a type of silica that lacks a distinct crystal structure and therefore appears as a glass-like material. Other synonyms for amorphous silica include hydrated silica, precipitated silica, and fumed silica. Regardless of the term used, amorphous silica is widely used in industries such as construction, electronics, and pharmaceuticals due to its unique properties and versatility.
