Description

Products Description

It is a byproduct of the smelting of silicon and is commonly used as an additive in concrete to enhance its strength and durability. Silica Fume's excellent thermal insulation properties make it suitable for high-temperature applications, including furnace linings, kiln linings, and other high-temperature equipment. Its small particle size and high surface area provide efficient thermal insulation, as well as good refractory properties that can withstand extreme temperatures. Additionally, Silica Fume is fire-resistant, non-combustible, and non-toxic, making it a safe and popular choice for various industrial applications.
