| HAFNIUM NITRIDE Basic information |
| HAFNIUM NITRIDE Chemical Properties |
Melting point | 3305°C | density | 13.800 | form | yellow-brown cubic crystals | color | yellow-brown cubic crystals, crystalline | Resistivity | 33 (ρ/μΩ.cm) | Crystal Structure | Cubic | EPA Substance Registry System | Hafnium nitride (HfN) (25817-87-2) |
| HAFNIUM NITRIDE Usage And Synthesis |
Chemical Properties | yellowish brown crystal(s); fcc, a=0.4518nm; most refractory of all known metal nitrides; hardness 1640kgf/mm2; electrical resistivity 33μohm· cm; can be prepared by heating Hf in N2 or NH3 atmospheric at 1000°C–1500°C; as a 99.5% pure material, used as a sputtering target to increase electrical stability of diodes, transistors, and integrated circuits [KIR80] [KIR81] [HAW93] [CER91] | Chemical Properties | Hafnium nitride is formed as yellow-brown, cubic crystals
and is prepared by heating hafnium metal to 1000–1500 C
in an atmosphere of nitrogen or ammonia. It can also be
prepared by reacting hafnium tetrachloride vapor with nitrogen
in a hydrogen atmosphere at temperatures higher than
1000 C.
Hafnium nitride is a brittle solid. The deposition of a thin
layer of hafnium nitride on steel grade, cemented carbide,
cutting tools reduces frictional forces and wear, thus increasing
the life of the tool by a factor of 6–8. | Physical properties | Most refractory of all nitrides. |
