Description of Niobium Nitride NbN Powder :

First, niobium nitride has a very high hardness, second only to diamond and boron nitride, and its hardness value can reach 2500HV. This high hardness makes niobium nitride widely used in manufacturing cutting tools, cutting tools, wear parts, etc.

Secondly, niobium nitride has good electrical and thermal conductivity, and its electrical and thermal conductivity are higher than metal materials such as stainless steel and copper. This excellent electrical and thermal conductivity makes niobium nitride have many applications in the manufacture of electronic devices, such as integrated circuit chips, thermoelectric converters, etc.

In addition, niobium nitride has good corrosion resistance and can be used in high-temperature and corrosive environments. This characteristic makes niobium nitride have a wide range of applications in aerospace, energy, and other fields, such as high-temperature stoves, thermocouples, resistors, lithium battery anode materials, fuel cell electrode materials, etc.

In addition, the chemical stability of niobium nitride is also excellent; it does not react with acids, bases, salts, and other substances at room temperature and only responds with a few gases, such as hydrogen, oxygen, and chlorine, at high temperatures. This chemical stability makes niobium nitride widely used in the chemical industry, environmental protection, and other fields, such as manufacturing chemical reaction vessels, catalyst carriers, etc.

In addition, the physical properties of niobium nitride include low density, high elastic modulus, and low thermal expansion coefficient. These properties make niobium nitride widely used to manufacture lightweight, high-strength materials, precision instruments, etc.

Production Method of Niobium Nitride NbN Powder ：

Raw material preparation

The following raw materials are required for the production of niobium nitride:

Niobium powder: as a primary raw material, it requires high purity, fine particle size, and good activity.

Nitrogen: As a nitriding source, it requires high purity and stable pressure.

Catalyst: Used to promote nitriding reaction, commonly used alkali metal salts, alkali metal oxides, etc.

Preparation of niobium nitride powder

There are two main methods for preparing niobium nitride powders: direct nitriding and carbide nitriding.

Direct nitriding method: niobium powder reacts with nitrogen at high temperature to direct nitride into niobium nitride. The reaction temperature is usually above 1000 ° C, and the reaction time depends on the degree of nitriding required. The niobium nitride powder prepared by this method has high purity and fine particle size. Still, the production cycle is long, high-temperature conditions are needed, and equipment requirements are high.

Carbide nitriding method: niobium carbide reacts with nitrogen at high temperatures to produce niobium nitride and cyanide. The reaction temperature is usually above 1000 ° C, and the reaction time depends on the degree of nitriding required. The niobium nitride powder prepared by this method has high purity and fine particle size. Still, harmful substances such as cyanide will be produced in the production process, which needs to be treated for environmental protection.

Forming and sintering

The prepared niobium nitride powder must be molded and sintered to obtain the desired shape and properties.

Molding: Niobium nitride powder is placed into a mold and pressurized to form the desired shape and size. The molding pressure depends on the requirements of the product and generally needs to be between several tons and tens of tons.

Sintering: The formed niobium nitride body is sintered at high temperatures to obtain the required strength and density. The sintering temperature is usually above 1000℃, and the sintering time is determined according to the product requirements.

Post-processing

After sintering, the resulting niobium nitride product must be post-treated to remove surface impurities and defects and improve product performance.

Surface treatment: Using sandblasting, polishing, and other methods to remove surface impurities and defects improves the surface smoothness and cleanliness.

Heat treatment: Heat treatment at a specific temperature to improve the mechanical and electrical properties of niobium nitride. Heat treatment temperature and time according to product requirements.

Coating treatment: The niobium nitride surface is coated with one or more layers of other materials to improve the properties of niobium nitride or to meet specific application requirements. The coating material can be metal, non-metal, or composite material.
