Technology Process of Lithium silicon

There total 3 articles about Lithium silicon which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

lithium (7439-93-2) + silicon (7440-21-3) → lithium monosilicide (68848-64-6)

Guidance literature:

In neat (no solvent); High Pressure; Ar-atmosphere; heating at 600°C in pressure of 40 kbar for 5 min,rapidly quenching to room temp. before pressure releasing; detd by X-ray diffraction, difference thermal analysis;

Reference yield:

lithium (7439-93-2) + silicon (7440-21-3) → Li12Si7 + lithium monosilicide (68848-64-6)

Guidance literature:

In neat (no solvent); High Pressure; under inert atm.; at 2 GPa; temp. 250°C; 1.8Li:1.0Si in starting material; 16 h run time; mixt. of Li and Si were first heated to 400°C in ZrO2 crucible; then packed into stainless steel capsules for high P-T treatment; monitored by X-Ray diffraction;

DOI:10.1016/S0022-4596(03)00045-8

Reference yield:

Li12Si7 + silicon (7440-21-3) → lithium monosilicide (68848-64-6)
