What is hafnium Diboride Pulse?

Hafnium diboride can be described as an ultra-high-temperature ceramic that is made of hafnium, boron and other elements. The rare, high-quality ceramic is uncommon and has high heat conduction, electrical conductivity, and unusual characteristics. It is a metallic, grey substance. The hexagonal structure of hafnium diboride means that it melts at about 3,250 Celsius. The temperature and pressure are key factors in the resistance to oxidation of hafnium dioxide. Protective oxide layers form at 1500 degC and 1 atm pressure. HfB2 loses its antioxidant activity when it is exposed to temperatures above 1600°C or pressures below 1 atm. These conditions lead to B2O3 (one of the oxidation products of HfB2) boiling at a higher temperature, creating a protective layer.

Uses of hafnium Diboride Powder

HfB2 is able to be used for making ultra-high-speed fighter planes. It has both thermal and strength characteristics. HfB2 can be used to make aerodynamic forms and it doesn’t deteriorate upon reentry unlike other composites.

Hafnium diboride is also being studied to determine if it could be used in nuclear reactor control rods.

This barrier is also useful for diffusing microchips. The barrier may have less than 7 nanometers thickness if synthesized correctly.

Hafnium diboride powder characteristics


Hafnium boride (or simply hafnium boride) can be described as an ultra-high temperature ceramic that has boron or hafnium. It melts at about 3,250 degrees Celsius. Rare ceramic with high heat conductivity, and low electrical conductivity. Many of its characteristics are similar to titanium zirconium dioxide and zirconium triboride. It is metallic and gray. Hafnium Diboride’s hexagonal structure crystal structure is of a metallic gray color. It has a molecular density of 10.5g/cc.

How does hafnium Diboride Powder get made?

Below are steps for achieving combustion synthesis of high purity hafnium/diboride dust.

1. Make thinner by using base ingredients. Mix base ingredients with thinner.

2. Combining dry with wet

3. You should mix the graphite powder thoroughly. Cool the sealed pressure vessel by adding circulating water. This reaction can take place in vacuum at pressures between 0 to 5 MPa. You can transform raw materials into products using self-propagating combustion.

4. The product should be cooled. It is comprised of hafnium diboride as well as magnesium oxide. Hafnium triboride, after having removed magnesium oxide via pickling, is washed and rinsed in water. This is then passed through a filter to obtain hafnium diboride powder.
