acetylene black
A special type of @C00824@ formed by an exothermic @D01547@ of acetylene. It is characterized by the highest degree of aggregation and crystalline orientation when compared with all types of @C00824@.
Acetylene black must not be confused with the @C00824@ produced as a by-product during the production of acetylene in the electric arc process.
