Cerium Bromide Anhydrous CeBr3 CAS 14457-87-5 For Scintillation Crystal

Anhydrous cerium bromide is an important optical functional crystal material, which can convert high-energy particles or rays into pulsed fluorescence for radiation detection and analysis. This material is widely used in nuclear medicine imaging, safety inspection and other fields. One of the preparation methods is to prepare cerium bromide powder by dewatering bromination under the protection of HBr gas or NH4Br, and then cooling after melting in a protective atmosphere or vacuum. Compared with other methods, the anhydrous cerium bromide prepared by this method has low water content, and can effectively control the content of water, oxygen and other harmful impurities in the product. The operation is simple, the cost is low, and it is conducive to large-scale production.

Product Detail

product detail

Name: anhydrous cerium bromide, cerium bromide ultra dry CAS: 14457-87-5

Molecular formula: CeBr3 Molecular weight: 379.83

Description: Hydrobromide was dehydrated in HBr atmosphere. Introduce pure and dry HBr gas, heat hydrated bromide, and balance with NH4Br. The temperature rises slowly to 250 ℃, by which time most of the water has been removed. Then slowly heat it to 600 ℃, and NH4Br has been completely sublimated to give cerium bromide anhydrous.
