    Fumed silica is a fine, powdery substance created by vaporizing silicon tetrachloride in a flame of hydrogen and oxygen. It’s known for its high surface area and unique properties such as thickening, anti-caking, and improving the flow of liquids and powders.
    Fumed silica is made through a process called flame hydrolysis, where silicon tetrachloride is burned in a hydrogen and oxygen flame, producing silicon dioxide (silica) in an ultrafine, amorphous form. This method results in fumed silica with very small particle sizes and a large surface area.
    Fumed silica is considered safe for use in various industries when handled properly. However, inhaling airborne particles can be harmful to the respiratory system, so it’s important to use appropriate personal protective equipment (PPE) like masks and ensure adequate ventilation when handling it in powder form.
    Fumed silica is widely used as a thickening agent, anti-caking agent, and to control the viscosity of liquids. It’s found in products ranging from cosmetics and pharmaceuticals to paints, coatings, and food. Its ability to enhance the properties of materials makes it valuable in numerous industrial applications.
