0 a soft, dark grey form of carbon, used in the middle of pencils, as a lubricant in machines, and in some nuclear reactors
1 a soft, dark gray form of carbon used in the center of pencils which makes a mark when pressed against something
Simple generation and detection of polyynes in an arc discharge between graphite electrodes submerged in various solvents.
Writing is best done with a fairly soft black graphite pencil.
We see that fully closed pore graphites prevents this contribution to hydrogen isotope inventory because there is no continuous surface leading deep into the graphite.
The advantage of graphite blanket is to exhibit 1ow activation, and in the case of the accident, released radioactivity is greatly reduced.
The mineral assemblage of the studied calcschist (sample 1435) comprises calcite, quartz, phengite, chlorite, albite and graphite.
The dicyanopolyyne series can be easily produced by arcing graphite electrodes into liquid nitrogen.
Direct observation of mosaic blocks in highly oriented pyrolytic graphite.
The graphite moderates the neutrons below activation energy levels.
