What is it?
Hafnium Diboride Powder
?
Hafnium boreide is a gray-colored crystal with metallic luster. It has high conductivity, and stable chemical property. It is indistinguishable from all other chemical reagents at room temperature, with the exception of hydrofluoric acids. It can be prepared by heating hafnium oxide, boron carbonide, and carbon powder. It is used to make superalloys.
The key features of Hafnium Diboride Powder
Hafnium Diboride is known for its high melting point, high hardness and excellent electrical and thermal conductivity. It also has high neutron absorption and performance. It can be used to make electrode materials, neutron absorption materials, ultra-high-temperature materials, and super-hard materials.
Applications of Hafnium Diboride Pulver
1. Hafnium Diboride in wear-resistant coats Because of its exceptional fire resistance, it can also be used in ultra high temperature composite materials (SiC) with silicon carbide. This material is more resistant to oxidation when it has been combined with silicon carbide.
2. The temperature and pressure determine the resistance to oxidation of hafnium dioxide. At 1500 degrees Celsius and 1 atmosphere pressure, a protective oxide of hafniumoxide is formed. HfB2’s oxidation resistance will decrease significantly if it is heated above 1600 degrees Celsius and the pressure is below 1 atmosphere. These conditions will cause the boiling temperature for B2O3, one of the HfB2 oxidation products, to exceed 1200°C. A protective oxide layer will then form.
3. Because of its strength and thermal characteristics, HfB2 can be used in ultra high-speed reentry vehicle, such as heat shields, for intercontinental ballistic missiles, or aerodynamic fronts. HfB2 forms aerodynamic shapes unlike composite and polymers, and does not ablate during reentry.
4. Hafnium Diboride has been also investigated as a possibility for new materials in nuclear reactor control rods.
5. Hafnium-diboride is being investigated as a diffusion barrier for microchips. If the synthesis is correct the barrier thickness could be less than 7 nanometers. The supplier Hafnium Diboride Powder
