Silicon dioxide, often referred to as silica, is a naturally occurring compound composed of silicon and oxygen atoms (SiO2). It is one of the most abundant minerals on Earth and exists in various forms, including quartz, sand, and glass. Silicon dioxide is a versatile material with applications spanning multiple industries. In the electronics industry, it is used as an insulator and substrate in semiconductor devices. In construction, it is a key component in concrete and building materials. It is also employed in the production of glass, ceramics, and abrasives. Additionally, silicon dioxide has applications in the food and pharmaceutical industries as an anti-caking agent and flow aid. Its wide availability and diverse properties make silicon dioxide an indispensable material in numerous industrial and consumer applications.
Silicon Dioxide, E551, CAS no.7631-86-9, white powder. Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth's most abundant materials: silicon (Si) and oxygen (O2). Silicon Dioxide is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications used in silica gel, control moisture levels to avoid prevent certain goods from going bad. It is often used in cheese, fat spreads, confectionery, dried vegetables, etc. As an experienced Silicon Dioxide manufacturer and supplier, we has been supplying and exporting Silicon Dioxide for almost 10 years, please be assured to buy from us.
