Abstract
Disclosed is a method for manufacturing a precursor composition of a silicon carbide-containing material, wherein nanoscale silicon dioxide, in particular fumed silica, and nanoscale carbon, in particular carbon black, are mixed. Also disclosed are a precursor composition manufactured in this way, a method for manufacturing a silicon carbide-containing material from the precursor composition and a silicon carbide-containing material manufactured in this way.
Claims11
A method of manufacturing a precursor composition for the manufacture of a silicon carbide-containing material, comprising:
- first mixing nanoscale silicon dioxide and nanoscale carbon to form a mixture having a desired mass ratio;
- subsequently adding a solvent to the mixture and mixing the mixture;
- and
- drying the mixture,
- wherein the desired mass ratio of carbon to silica is in the range from 2.4:1 to 3.1:1.
