Description of Hafnium Nitride HfN Pulver:

Physical properties:

Structure: The crystal structure of hafnium nitride is similar to lanthanum nitride and hexagonal, but the lattice constant and atomic spacing are slightly different.

Color and form: Hafnium nitride is a black powder, similar to lanthanum nitride, but its appearance may be slightly different due to its unique crystal structure.

Hardness and conductivity: Hafnium nitride has a high hardness, with a Mohs hardness of about 7.5, comparable to lanthanum nitride. In addition, hafnium nitride also has good electrical conductivity.

Thermal stability: Hafnium nitride has high thermal stability and is not easily decomposed at high temperatures.

Chemical properties:

Gold properties: Hafnium nitride is a metal nitride that exhibits good gold properties. At room temperature, it is not easy to react with oxygen, water, etc. However, at high temperatures, it may respond to certain gases or liquids.

Stability: Hafnium nitride is stable at room temperature but may decompose at high temperatures. It is more durable than lanthanum nitride and, therefore, has advantages in some applications.

Optical properties: Hafnium nitride has high optical transmittance and good transparency to specific wavelengths of light.

Production Method of Hafnium Nitride HfN Powder：

High temperature and pressure method:

The high-temperature and high-pressure method is a standard method for preparing hafnium nitride. The method is to react with hafnium metal or hafnium alloy with nitrogen at high temperature and pressure to produce hafnium nitride. The specific steps are as follows:

Hafnium metal or hafnium alloy is made into powder or block to facilitate reaction with nitrogen gas.

The hafnium metal or hafnium alloy is placed in the nitriding furnace, and the cavity is sealed.

Nitrogen is fed into the furnace cavity to react with hafnium metal or alloy under high temperature and pressure.

Adjust the nitriding temperature and pressure to obtain high-purity and high-density hafnium nitride.

The advantages of the high temperature and high-pressure method are simple processes and low cost. Still, the disadvantage is that the reaction conditions are higher, and the operation is more complicated.

Laser pulse method:

The laser pulse method is an advanced method for preparing hafnium nitride. The technique uses laser pulses to irradiate hafnium targets and combine hafnium atoms with nitrogen atoms to form hafnium nitride. The specific steps are as follows:

The target is prepared into a hafnium metal or alloy target of a specific shape and size to facilitate laser irradiation.

Put the target into the vacuum chamber and keep the vacuum degree within a specific range.

By irradiating the target with the laser pulse, the surface of the target absorbs energy and heats up rapidly.

A nitriding layer of a certain thickness is formed on the surface of the target, and the thickness and purity of the nitriding layer are controlled by controlling the laser parameters and irradiation time.

The advantages of the laser pulse method are fast reaction speed, good controllability, and high purity. Hafnium nitride can be prepared, but the disadvantages are high equipment cost and technical difficulty.

Chemical vapor deposition method:

Chemical vapor deposition is a method of preparing thin film materials by reacting a mixture of gases containing hafnium compounds and nitrogen at high temperatures to produce a thin hafnium nitride film. The specific steps are as follows:

A mixture of hafnium compounds and nitrogen is passed through a reaction chamber to react at high temperatures to produce a thin film of hafnium nitride.

Adjust reaction temperature and time to obtain high-purity and high-density hafnium nitride film.

The resulting hafnium nitride film is removed from the reaction chamber and post-treated.

The advantage of chemical vapor deposition is that a large area and high-purity hafnium nitride film can be prepared. Still, the disadvantage is that the process could be more straightforward, and the cost is high.
