HAFNIUM CHLORIDE Usage And Synthesis
Chemical Properties white fine crystalline powder
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.
Uses Hafnium tetrachloride is an important intermediate in production of hafnium metal. It also is used to prepare many hafnium compounds.
Uses Hafnium chloride tetrahydrofuran complex is an efficient catalyst for the Diels-Alder cycloadditions, Ziegler-Natta polymerization of alkenes. It is used as control rods in nuclear reactors and in manufacture of light bulb filaments.
Uses

Hafnium (IV) chloride can be used to catalyze the direct ester condensation of carboxylic acids with alcohols effectively.

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.
