What is hafnium Diboride Powder?
Hafnium Diboride is an ultra-high-temperature ceramic that is made from hafnium, boron. It is a unique ceramic with high heat conductivity and conduction. It is a metallic gray color. Hafnium dioxide has a hexagonal structure and a density 10.5 g/cc. It can melt at approximately 3,250 degrees Celsius. Hafnium diboride’s resistance to oxidation is affected by temperature and pressure. At 1500°C and 1atm, there is a protective oxide layer. HfB2’s antioxidant activity decreases when temperatures rise above 1600degC and pressure drops below 1atm. In these conditions, B2O3 which is one of the oxidation products from HfB2’s heats up to boiling point and forms a protective layer of oxide.
Uses of hafnium diboride powder
Because of its strength and thermal characteristics, HfB2 can be used in ultra high-speed reentry aircrafts, such as an INTERCONTINENTAL missile heat shield or pneumatic front. HfB2 has an aerodynamic form and doesn’t ablate upon reentry, unlike polymers and composites.
Hafnium Diboride is being considered as a new material to be used in nuclear reactor control rods.
It is also being investigated as a diffusion shield for microchips. If the barrier is correctly synthesized, it can be less than seven nanometers thick.
Hafnium diboride powder characteristics
:
Hafnium Diboride is an ultra-high-temperature ceramic that’s made of hafnium, boron. It melts at approximately 3,250 degrees Celsius. It is an unusual ceramic that exhibits high heat conduction, electrical conductivity, and the same properties as zirconium diboride and titanium. It is a gray, metallic substance. Hafnium Diboride has hexagonal crystal structures with a molar density of 10.5 g/cc and a mass of 200.11g/mol.
How is hafnium Diboride powder manufactured?
These are the steps that enable you to realize combustion synthesis for high purity hafnium Diboride Powder.
1. Mix base ingredients and thinner. Mix base ingredients with thinner.
2. Dry and mix
3. The graphite powder should be evenly mixed. The reaction is then carried out in a closed pressure vessel under 0-5MPa pressure, or in a vacuum with a protective atmosphere. By self-propagating burning, raw materials can be transformed into products.
4. Cool the product. It is a mixture between hafnium dioxide and magnesium oxide. To obtain hafnium Diboride powder, magnesium oxide must be removed by picking.
