What’s hafnium Diboride Powder?
Hafnium diboride can be described as an ultra-high-temperature ceramic that is made of hafnium, boron and other elements. It’s an uncommon ceramic that has high heat conductivity and conduction. It is a grey, metallic substance. Hafnium dioxide has a hexagonal structure and melts at approximately 3,250 Celsius. Hafnium diboride’s resistance to oxidation is affected by temperature and pressure. At 1atm pressure and 1500 degC, the protective oxide scale is formed. HfB2’s antioxidant activity decreases when temperatures rise above 1600degC, and pressure drops below 1atm. In these circumstances, B2O3 (one oxidation product of HfB2) boils at a higher temperature than B2O3, creating a protective layer of oxide.
Uses of hafnium diboride powder
Because of its thermal and strength properties, HfB2 can be used to make ultra-high-speed fighter jets. HfB2 has an aerodynamic form and doesn’t ablate upon reentry, unlike polymers and other composites.
Hafnium diboride has also been studied in an effort to find a new material that could be used as nuclear reactor control rods.
The barrier can also be used to diffuse microchips. It can have a thickness of less than 7 nanometers, if it is synthesized correctly.
Hafnium diboride powder characteristics
Hafnium diboride (or hafnium diboride) is an ultra high temperature ceramic that is made of hafnium, boron. It melts at approximately 3,250 degrees Celsius. It’s an uncommon ceramic that has high heat conductivity and low electrical conductivity. This material shares many of the same characteristics as zirconium diboride and titanium. It’s gray and metallic. Hafnium diboride’s hexagonal crystal structure has a molar density of 10.5 g/cc and a mass of 200.11g/mol.
How does hafnium Diboride Powder get made?
Here are the steps to realize combustion synthesis high purity hafnium-diboride powder:
1. Use base ingredients to make thinner. Combine base ingredients with thinner.
2. Combine dry with wet
3. The graphite powder should be evenly mixed. Once the closed pressure vessel has been cooled, add circulating water to cool it. The reaction takes place under vacuum or pressure of 0-5 mpa. By self-propagating combustible combustion, raw materials can be transformed into products.
4. Cool the product. It is composed of hafnium oxide and magnesium diboride. After removing magnesium oxide by picking, hafnium triboride is washed in water. Then it is filtered through a filter and dried to make hafnium biboride powder.
