Lithium Sulfide is white to yellow crystals, which have smell of sulfur. It is typical sulfide of lithium. It is stable at home temperature and pressure, however react with water sharply. Li2S tend to absorb moisture in air and oxidize. When heating to 200℃, Li2S react with iodine and form lithium iodide. It react with carbon in electric-arc furnace and form lithium carbide. Lithium metal and pure sulfur are the raw materials.
