Physical and Chemical Properties | Lithium oxide (Li2O) is a white powder or hard shell solid, ionic compound. Relative density of 2.013, melting point of 1567 ℃, boiling point of 2600 ℃,1000 ℃ above sublimation, easy deliquescence, soluble in water, hygroscopic and corrosive, in the air is very easy to absorb carbon dioxide and water, lithium hydroxide LiOH with strong alkalinity is produced; It can corrode glass and certain metals at high temperatures. Lithium oxide can be reduced to elemental lithium by a metal such as silicon or aluminum, and can also react with an acid to form a lithium salt. Lithium oxide is a hazardous chemical and is marked as "corrosion". lithium oxide is widely used in lithium batteries, glass ceramics, lithium chemical industry, nuclear industry and other fields. In the field of lithium batteries, battery-grade lithium oxides are mainly used as electrolyte materials for solid-state lithium batteries and cathode materials for lithium-ion power batteries. In the field of glass ceramics, lithium oxide is mainly used as an additive to improve the properties of glass ceramics. |

white powder. The relative density was 9. 42. Melting point 2467 °c. Insoluble in water, soluble in acid. It is easy to absorb carbon dioxide and moisture in the air.
extraction method: the rare earth nitrate solution containing Y2 03 50%, CeO2 about 4% and cerium removed from Brown yttrium niobium ore is used as the raw material, the yttrium-rich rare earth is obtained by N263-LiNO3 system extraction, after acid dissolution, then the pure yttrium is extracted by N263-heavy solvent-NH4 SCN system, the raffinate is yttrium-rich rare earth, thulium, ytterbium, (3) the heavy rare earth enters the organic phase, and then the Thulium is extracted by N263-heavy solvent to group the thulium, and the thulium ytterbium is back-extracted with hydrochloric acid to enter the aqueous phase. After separation, further, it is back-extracted with hydrochloric acid to make hydrazine enter the aqueous phase, and then precipitated by oxalic acid, filtered and burned to prepare hydrazine oxide.
It is mainly used as an additive element of yttrium iron and yttrium aluminum garnet and an active material of a fluorescent powder. It is also used in the manufacture of special alloys.
polyethylene plastic bottle packaging, jacket carton protection. Log or 500g net weight per bottle. Should be stored in a ventilated, dry warehouse. During the storage and transportation process should pay attention to moisture and avoid package breakage. See cerium oxide products for toxicity and protection.
