Versuchsvorschrift

Although anhydrous hafnium nitrate and anhydrous zirconium nitrate are not currently commercially available, synthesis and purification techniques for these materials are known. Synthesis of zirconium nitrate was reported in 1962. Due to the similarities between hafnium and zirconium, hafnium nitrate may also be isolated through a similar synthesis process. Hafnium nitrate may be prepared by refluxing hafnium tetrachloride over dinitrogen pentoxide at 30° C., and then purified by sublimation at 100° C./0.1 mmHg for hafnium nitrate. Zirconium nitrate can be similarly purified at 95° C./0.1 mmHg.
