  • Calibration of the Lutetium-Hafnium Clock - JSTOR
    hafnium ages that are based on the previously used 176Lu of 1 93 X 10-11 to 1 94 X 10-11 year-1 are thus -4% too young, and the initial hafnium isotope compositions of some of Earth's oldest minerals and rocks become less radio-genic relative to bulk undifferentiated Earth when calculated using the new decay constant

  • The Chemistry behind Room Temperature Synthesis of Hafnium . . .
    hafnium is a close analogue of zirconium; both are transition metals with similar atomic radii, physicochemical properties, and coordination chemistry 17 However, they differ in one key regard: Hf has slower reaction kinetics and forms stronger M-O bonds than Zr, and this feature directly affects synthesis with these metals 17
