Abstract

Carbon blacks containing silicon and a process for manufacturing them. The carbon blacks containing silicon are suitable as reinforcing carbon blacks for rubber mixtures and give the latter viscoelastic properties such as reduced rolling resistance in tires. At the same time, the wet traction is even improved in the process.
