WebLi 2 O Molar mass: 29.88 g/mol Appearance white solid Density: 2.013 g/cm 3: Melting point: 1,438 °C (2,620 °F; 1,711 K) Boiling point: 2,600 °C (4,710 °F; 2,870 K) Web2 LiOH + CO2 → Li2CO3 + H2O. The latter, anhydrous hydroxide, is preferred for its lower mass and lesser water production for respirator systems in spacecraft. One gram of anhydrous lithium hydroxide can remove 450 cm 3 of carbon dioxide gas. The monohydrate loses its water at 100–110 °C.

Lithium hydride is an inorganic compound with the formula LiH. 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, … WebThermal conductivity of Lithium is 85 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction. Note that Fourier’s law applies for all matter ...
