Lead Monoxide

Lead monoxide is an inorganic compound. It is produced on a large scale as an intermediate in the conversion of lead ores, mainly galena into metallic lead. The consumption of lead, and hence the processing of PbO, correlates with the number of automobiles because it remains the key component of automotive lead-acid batteries. It is used extensively in manufacturing of lead glasses and ceramic glazes as well as in fine dinnerware. Other less dominating applications include the vulcanization of rubber and the production of certain pigments and paints. It is used in cathode ray tube glass to block X-ray emission, but mainly in the neck and funnel because it can cause discoloration when used in the faceplate. Strontium oxide is preferred for the faceplate. PbO is used in certain condensation reactions in organic synthesis.

Lithium Aluminium Hydride

Lithium aluminium hydride is an inorganic compound. It was discovered by Finholt, Bond and Schlesinger in 1947. This compound is used as a reducing agent in organic synthesis, especially for the reduction of esters, carboxylic acids, and amides. The solid is dangerously reactive toward water, releasing gaseous hydrogen.

Lithium Carbonate

Lithium carbonate is a chemical compound of lithium, carbon, and oxygen. It is widely used in the processing of metal oxides and has received attention for its use in psychiatry. It is an important industrial chemical. It forms low-melting fluxes with silica and other materials. It is a common ingredient in both low-fire and high-fire ceramic glaze. Cement sets more rapidly when prepared with lithium carbonate, and is useful for tile adhesives. It is used as an active material of carbon dioxide sensors. It is also used in the manufacture of most lithium-ion battery cathodes, which are made of lithium cobalt oxide.

Lithium Sulfide LAB GRADE 99%

Lithium Sulfide

 

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.
