BRITEFUME – Technical Co.
Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). Its individual particles are extremely small, approximately 1/100th the size of an average cement particle. It therefore effectively fills in empty pores in the cement and helps produce a stronger, more compact material.
Silicon dioxide – Wikipedia
Silicon dioxide, also known as silica, silicic acid or silicic acid anydride is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms.

Silicon Dioxide, High Purity (SiO2) Silica Sand – Reade
Silica is manufactured in several forms including glass, crystal, gel, aerogel, fumed silica (or pyrogenic silica), and colloidal silica (e.g. Aerosil). In addition, Silica nanosprings are produced by the vapor-liquid-solid method at temperatures as low as room temperature.
What is Precipitated Silica | PPG Silica Products
Precipitated silica, a form of synthetic amorphous silicon dioxide, is derived from quartz sand, a crystalline form of silicon dioxide. The physical properties of precipitated silica can be manipulated during the manufacturing process to deliver products with a wide range of performance-enhancing features engineered for many different end-use applications.
