Spherical Hafnium Hf Powder Reference
Hf metal powder synthesis via a chemically activated combustion-reduction process
- The present study demonstrates the synthesis of fine hafnium (Hf) metal powders via a chemically activated combustion synthesis (CS) approach, which develops temperatures in the range of 1000–1600 °C. The current CS approach can be employed to obtain Hf powders with a single-crystalline hexagonal close-packed (hcp) structure in addition to high compositional uniformity and average particle sizes ranging from 0.05 to 2.0 μm. The mechanism of Hf particle formation can be understood by analyzing the process thermodynamics, including adiabatic temperatures and equilibrium reaction phases.
Hafnium and zirconium are transition metals. They resemble each other because they have similar chemical properties. The key difference between hafnium and zirconium is that hafnium has comparatively a low density, whereas zirconium has a high density.
Hafnium has good neutron-absorbing properties, and hence it is used in control rods in nuclear reactors. While hafnium nitride is the most refractory of all the metal nitrides, hafnium carbide is the most refractory of all the binary materials.
- High Melting Point: Hafnium has a melting point of 2,233°C, making it suitable for high-temperature environments.
- Corrosion Resistance: Excellent resistance to corrosion and oxidation, especially in reactive environments.
- Thermal Conductivity: Good thermal conductivity, beneficial for heat management applications.
- Reactivity: Can react with oxygen and other elements at elevated temperatures.
