Review of Hafnium Diboride Pulver
This is a gray crystal that has metallic luster. It exhibits high conductivity and is stable in chemical terms. It reacts well with most chemical reagents, except hydrofluoric acids at room temperature. Mixing hafnium dioxide with boron oxide and boron carbide to make it is possible, as well reducing hafnium trichloride and hafnium trichloride under 2000 hydrogen or directly reacting hafnium or boron. It can be used to make superalloys.
Hafnium-diboride’s melting points, hardness, electrical and thermal conductivity, and neutron absorption properties are all excellent. You will find it in many fields, including super-hard materials and electrode materials.
As technology advances, hafnium dioxide ceramics and other composite materials can be used in a wider range of applications. At home as well abroad, it is a major R&D priority to obtain low-cost but high-quality hafnium-diboride powder. Hafnium Diboride can be difficult to sinter. To improve the sintering efficiency, ultrafine powder must be obtained. While nanopowder offers superior performance, its cost is high and it can be difficult to disperse in raw materials processing. The development of submicron hafnium triboride powder attracted increasing attention.

What are the uses of Hafnium Diboride Powder?
Hafnium Diboride as wear-resistant coatings Because of its exceptional fire resistance, hafnium diboride is often used together with silicon caride (SiC), in ultra-high temperatures composite materials. This material is more resistant to oxidation when it has been combined with silicon carbide.
Hafnium diboride’s oxidation resistivity is affected by temperature and pressure. The protective oxide scale of hafniumoxide is formed when the temperature is 1500 degrees Celsius and the pressure at 1 atmosphere. HfB2’s oxidation resistance will decrease significantly if it is heated above 1600 degrees Celsius and the pressure drops to below 1 atmosphere. These conditions will cause the B2O3 (one oxidation product of HfB2) to boil above 1400C and the formation of a protective oxide layer.
Because of its thermal and strength, HfB2 can be used to make ultra-high-speed spacecraft, including heat shields, for intercontinental ballistic missiles, or aerodynamic fronts. HfB2 forms aerodynamic shapes unlike composite and polymers, and does not ablate upon reentry.
Hafnium diboride is also being studied for its potential as a material to be used in nuclear reactor control rods.
Hafnium Diboride is being investigated as a diffusion barrier in microchips. The barrier thickness could be lower than 7 nm, if all goes according to plan.
