Definition and Chemical Composition

White carbon black, chemically known as silica (SiO₂), is a white, non-toxic, amorphous powder that is a highly dispersed nanoscale nonmetallic material. Its unique properties stem from its chemical structure, which can be expressed as SiO₂·nH₂O, where nH₂O represents surface hydroxyl groups. This composition allows the material to exhibit both hydrophilic and hydrophobic characteristics, making it suitable for a wide range of applications.

Physical and Chemical Properties

Silica is a hard, brittle, non-conductive, and refractory material with a melting point of 1710°C. Its apparent density is 0.128 g/cm³, and it is insoluble in water. Chemically, silica is an anhydride of silicic acid and exhibits remarkable stability due to the strength of its silicon-oxygen bonds. It does not react with ordinary acids but is susceptible to corrosion by hydrofluoric acid. At high temperatures, silica can react with basic oxides, alkalis, and soda ash to form silicates, further demonstrating its reactivity under specific conditions.

Production Methods

The production of white carbon black involves two primary methods: the precipitation method and the vapor phase method. The precipitation method involves reacting sodium silicate solutions with acids to form silica colloids, which are then dried and sintered. This method includes traditional and special precipitation techniques, such as sol-gel and chemical crystal methods. The vapor phase method, on the other hand, decomposes silane or siloxane at high temperatures to generate silicon nanoparticles, resulting in fumed white carbon black with a purity of up to 99% and particle sizes as small as 10–20 nm. While the vapor phase method yields high-purity products, it is more complex and costly compared to the precipitation method.

Applications in Various Industries

The versatility of white carbon black is evident in its diverse applications across multiple sectors:

• Rubber Industry: As a rubber reinforcing agent, it enhances the strength, wear resistance, and aging resistance of rubber products, accounting for over 75% of its total usage.
• Coating Industry: It improves the adhesion, hardness, and wear resistance of coatings, making them more durable.
• Plastics Industry: Used as a filler, it enhances the strength and aging resistance of plastics.
• Catalyst Carrier: Its large specific surface area and activity make it ideal for catalytic applications.
• Environmental Protection: It acts as an adsorbent to remove harmful substances from water and degrades pollutants via photocatalytic reactions.
• Biomedical: With excellent biocompatibility, it is used in biomedical materials like scaffolds and drug carriers.
• Food Processing: As a food additive, it improves the taste and stability of food products.
• Paper Industry: It enhances the whiteness and printing performance of paper.
• Ink Industry: It improves the hiding power and stability of inks.
• Cosmetics Industry: It enhances the fineness and oil-regulating properties of cosmetics.
• Pharmaceutical Industry: It improves drug dispersion and bioavailability.
