US4137295A Carbide production using molten metals as

A process for carrying out highly endothermic chemical reactions wherein a reactive metal or a compound thereof is reacted with a source of carbon to form a carbon-containing derivative, preferably a carbide, in the presence of a molten metal. The sensible heat of the molten metal supplies the energy necessary for the reaction.

Composites Strengthened with Graphene SpringerLink

A very wide Raman band of lithium carbides with average FWHM about 41 cm −1 indicates the nanocrystalline form of Li 2 C 2 (Fig. 10 a). Lithium can also be present between graphene layers in platelets causing the formation of carbide Li x C 6. Such a process of lithium intercalation into carbon was observed in a typical Li-ion battery

In-operando Raman study of lithium plating on graphite

Nov 18, 2020· In-operando Raman spectroscopy with high spatial resolution (1 µm 2) was employed to study the lithium deposition reaction on graphite electrodes.The 1850 cm −1 acetylide band, which is always found on lithium metal spectra, appeared right after reaching the full lithiation of graphite, when the G and D bands of graphite vanished. The band was observed during potestiostatic overcharge at

Lithium hydride Wikipedia

Lithium hydride is an inorganic compound with the formula Li H.This alkali metal hydride is a colorless solid, although commercial samples are grey. Characteristic of a salt-like (ionic) hydride, it has a high melting point, and it is not soluble but reactive with all protic organic solvents. It is soluble and nonreactive with certain molten salts such as lithium fluoride, lithium borohydride

How is carbon dioxide eliminated aboard a spacecraft

On Earth, plants remove carbon dioxide through the process of photosynthesis. The plants take in carbon dioxide and release oxygen. However, in a spacecraft, carbon dioxide must be removed from the cabin air through chemical processes. Most spacecraft rely solely on removing the carbon dioxide with canisters that contain powdered lithium hydroxide.

Acetylene Wikipedia

The carbonaceous material in an archeological sample is treated with lithium metal in a small specialized research furnace to form lithium carbide (also known as lithium acetylide). The carbide can then be reacted with water, as usual, to form acetylene gas to feed into a mass spectrometer to measure the isotopic ratio of carbon-14 to carbon-12.
