A notable physical difference between these metals is their density, with zirconium having about one-half the density of hafnium. The most notable nuclear properties of hafnium are its high thermal neutron capture cross section and that the nuclei of several different hafnium isotopes readily absorb two or more neutrons apiece.

Density of Hafnium (Hf) is 13310 kg/m3 . Volumetric mass density of Hafnium (Metal, alloy) in other popular units: = 13.31 [kg/L] or [g/mL] or [g/cm3] or [t/m3] = 7.69366810432 [oz/cu in] (Avoirdupois ounce per cubic inch) = 13.8846667036 [oz/US fl oz] (Avoirdupois ounce per fluid ounce) = 0.48085425652 [lb/cu in] (Avoirdupois pound per cubic inch)

Hafnium, chemical element, metal of Group 4 (IVb) of the periodic table. It is a ductile metal with a brilliant silvery luster. It is dispersed in Earth’s crust to the extent of three parts per million and is invariably found in zirconium minerals up to a few percent compared with zirconium.

One physical difference between hafnium and zirconium is their density. Zirconium has approximately half the density of hafnium. Separating hafnium and zirconium is incredibly …

2025年1月27日 · Hafnium is a lustrous silvery, ductile metal typically found in the 4+ oxidation state. It is poorly soluble in water as a pure metal. It is relatively unreactive to alkalis and strong acids, except hydrofluoric acid and is frequently alloyed with iron, niobium, tantalum, and titanium.

Density of Hafnium is 13.31g/cm3. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V. Electron affinity of Hafnium is …

Hafnium metal has no known toxicity. The metal is completely insoluble in water, saline solutions or body chemicals. Exposure to hafnium can occur through inhalation, ingestion, and eye or …
