Lithium hydride melting point
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 … Meer weergeven LiH is a diamagnetic and an ionic conductor with a conductivity gradually increasing from 2×10 Ω cm at 443 °C to 0.18 Ω cm at 754 °C; there is no discontinuity in this increase through the melting point. The dielectric constant Meer weergeven LiH powder reacts rapidly with air of low humidity, forming LiOH, Li2O and Li2CO3.
