13499-05-3 Usage

Uses

Hafnium tetrachloride is an important intermediate in production of hafnium metal. It also is used to prepare many hafnium compounds.

Preparation

Hafnium tetrachloride can be prepared (i) by chlorination of hafnium dioxide in the presence of carbon: HfO2 + 2Cl2 + C → HfCl4 + 2CO It also may be prepared by several other methods, such as (ii) reaction of carbon tetrachloride with hafnium dioxide above 450°C; (iii) heating a mixture of hafnium dioxide and carbon above 700°C; and (iv) reaction of chlorine with hafnium at elevated temperatures.

Physical properties

White monoclinic crystal; sublimes at 317°C; melts at 432°C at 33 atm (triple point); critical temperature 452.5°C; critical pressure 53.49 atm; critical volume 314 cm3/mol; hydrolyzes in water.

Chemical Properties

white fine crystalline powder

Preparation, structure and scintillation of cesium HAFNIUM CHLORIDE (cas 13499-05-3) bromide crystals08/08/2019

We report on the preparation, structure and scintillation properties of single crystal cesium hafnium chloride bromide (Cs2HfCl4Br2 or CHCB). The crystals were grown using a vertical Bridgman technique process. Single crystal X-ray diffraction showed that the as grown CHCB crystal structure was ...detailed
