Silica is an abundant mineral found in the Earth's crust and is a major component of sand, rocks, and other natural materials. It is often used in the manufacture of glass, ceramics, and abrasive materials. Silica exists in two main forms: crystalline and amorphous.
Crystalline Silica
Crystalline silica is a naturally occurring form of silica that has a crystalline structure. This type of silica is often found in nature as quartz, and is the most common form of silica used industrially. It is used in the manufacture of glass, ceramics, abrasives, and other products.
Amorphous Silica
Amorphous silica is a non-crystalline form of silica and is commonly found in nature as diatomaceous earth, clay, or volcanic ash. It is used primarily in the manufacture of abrasives, catalysts, and fillers. It is also used in the production of silica gel, which is used as a desiccant.
