Lanthanum Bromide Anhydrous LaBr3 CAS 13536-79-3 For Scintillation Crystal

Anhydrous lanthanum bromide (LaBr₃), a white crystalline powder, is an important chemical with a relative density of 5.06, a melting point of 783°C, and a boiling point of up to 1577°C. It is soluble in water and ethanol, but insoluble in ether. Anhydrous lanthanum bromide has important applications in the field of optical functional crystals, especially in the production of scintillation crystals, and its excellent properties have been widely concerned. In addition, because anhydrous lanthanum bromide is easily polluted by moisture and aerobic substances, the preparation technology is difficult and requires strict preparation technology and packaging treatment.

Product Detail

product detail

Name: anhydrous lanthanum bromide, lanthanum bromide ultra dry CAS: 13536-79-3

Molecular formula: LaBr3 Molecular weight: 378.62

Description: The lanthanum oxide or hydroxide is dissolved in hydrobromic acid, evaporated, concentrated, cooled, washed with ethanol and ether to obtain its hexahydrate. The latter is dehydrated iwith ammonium bromide, and then heated in the helium gas stream at 600 ℃ to obtain the anhydrous lanthanum bromide. Safety instructions: in case of contact with eyes, immediately wash with plenty of water and send to a doctor for treatment; wear appropriate protective clothing.Hazard Code: R36 / 37 / 38: irritating to eyes, respiratory tract and skin.
