Silica is a rubber filler Lane, which would increase the corrosion resistance of the rubber. It is mainly based on coal tar as raw materials under high temperature pyrolysis and women.

The thermal technologies included high temperature over-burning, infrared destruction, plasma arc pyrolysis, molten salt destruction, supercritical water oxidation, in situ vitrification, and etc.

Upon pyrolysis of organic aerogel powder at high temperature, the carbonized aerogel can be obtained.
