It is this extremely reactive atomic oxygen species that allows piranha solution to dissolve elemental carbon.

"Dry" Particulate emissions are also known as inorganic soot, black carbon, or elemental carbon.

Replies: Pencil "lead" is actually graphite (elemental carbon) with probably some other things in it.

Lead and elemental carbon do not normally combine, even at very high temperatures.

It was almost, but not quite, pure silica and iron with some traces of elemental carbon.

One problem is that the production of elemental carbon tends to foul the catalyst's surface, which is detrimental to the reaction's efficiency.

The process involves high temperature reduction with elemental carbon in an electric arc furnace:

In chemistry, it refers to matter composed of only one chemical element: graphite and diamond are both forms of elemental carbon.

Organic matter and elemental carbon together constitute the carbonaceous fraction of aerosols.
