White carbon black: a material revolution from laboratory to industrial applications
Core characteristics: White carbon black (SiO ₂ · nH ₂ O), as an inorganic non-metallic material, has become a core raw material for multifunctional additives in various fields due to its nanoscale particle size (10-200nm), ultra-high specific surface area (150-700m ²/g), and surface hydroxyl structure. Its chemical inertness, high temperature resistance (melting point 1600 ℃), and insulation (resistivity>10 ¹⁴Ω· cm) make it stable in extreme environments.
Industrial applications:


Rubber industry: As a key reinforcing agent for "green tires", it can reduce rolling resistance by 30% while improving wet skid resistance and wear resistance. For example, Michelin tires made from gas-phase white carbon black have a 5% increase in fuel efficiency.
In the field of coatings, gas-phase white carbon black forms a three-dimensional network structure, which extends the weather resistance of exterior wall coatings to 10 years and increases coverage by 40%.
New energy battery: As a negative electrode additive for lithium-ion batteries, its porous structure increases battery capacity by 15% and has a cycle life exceeding 2000 times.
Technical breakthrough: Koning Chemical has increased the specific surface area of white carbon black to 800m ²/g through the sol gel method. After being applied to supercapacitor electrodes, the energy density has reached 12Wh/kg, nearly three times that of traditional lead-acid batteries.
