White Carbon Black, chemically recognized as silica (SiO₂), is a high-performance, non-toxic, amorphous white powder. As a highly dispersed nanoscale nonmetallic material, it serves as a premium alternative to traditional carbon black, offering exceptional purity and a porous structure characterized by surface hydroxyl groups (SiO₂·nH₂O) that enhance its chemical reactivity and bonding capabilities.
Engineered for versatility, our industrial-grade white carbon black is produced via advanced precipitation and vapor phase methods to ensure precise particle size and high stability. From reinforcing rubber and plastics to enhancing the stability of cosmetics and pharmaceuticals, this material provides critical functional improvements in hardness, wear resistance, and dispersion across a wide spectrum of industrial applications.

Frequently Asked Questions
White carbon black is a specialized form of amorphous silica (SiO₂) designed for high dispersion and specific surface area, allowing it to function as a reinforcing agent similar to carbon black but with a white appearance.
It acts as a reinforcing agent that enhances the tensile strength, abrasion resistance, and aging properties of rubber, accounting for over 75% of its industrial application.
Yes, due to its non-toxic nature and good biocompatibility, it is widely used in cosmetics to regulate oil and in pharmaceuticals to improve drug stability and bioavailability.
The two main methods are the Precipitation method (reacting sodium silicate with acid) and the Vapor Phase method (decomposing silane/siloxane at high temperatures) for higher purity.
Absolutely. Its porous structure makes it an excellent adsorbent for removing harmful substances from water and a catalyst carrier for degrading air pollutants.
Silica powder is chemically stable. It should be stored in a cool, dry place in sealed containers to prevent moisture absorption and maintain its amorphous properties.
