In the crystal structure of the title compound, [Hf(C(5)H(5))(3)], three cyclo-penta-dienyl ligands surround the Hf(III) atom in a trigonal-planar geometry. The mol-ecule lies on a sixfold inversion axis.

The results of a laser ablation microprobe–inductively coupled by the more widely used samarium–neodymium system (e.g. Dickin, 1995). As a tracer of petrogenetic processes, plasma mass spectrometry Lu–Hf isotope study of zircons in however, Lu–Hf has one important advantage over Sm– 0·93–1·67 Ga rocks from south Norway indicate that early Nd: zircons retain a robust memory of their initial Hf P...

A bomb process for preparing zirconium and hafnium metals with calcium by the reduction of their tetrafluorides is described. A detailed method of preparing the high purity tetrafluorides is presented and the purity and physical properties of the metals obtained are discussed.

Nanostructured single-phase hafnium-zirconium carbonitride powders were synthesized using a simple and fast mechanochemical synthesis approach. The critical milling duration, after which (Hf,Zr)(C,N) solid solution formation inside jar occurred via mechanically induced self-sustained reaction (MSR), was 10 min. After 30 min of treatment, solid-gas completed, as result, homogeneous powder consis...
