A carbon-based black soot produced from the burning of acetylene. Acetylene black is produced in anaerobic refractory chambers by the decomposition of acetylene gas preheated to 800° C (1,500° F). It is primarily used in applications requiring high electrical conductivity, such as dry cells. Acetylene black is also used in printing inks, as a filler in rubber and gloss suppressant in paints.
