Zirconium Nitride 

CAS number: 25658-42-8 

Molecular formula: ZrN 

Molecular weight: 105.23 

Characteristic: Light yellow cubic crystal, belonging to the sodium chloride type structure. 

Density (g/mL, 25/4 ℃): 7.09 

Melting point (º C): 2960 

Solubility: soluble in concentrated hydrofluoric acid, concentrated sulfuric acid, and hot alkali, slightly soluble in dilute hydrochloric acid and dilute sulfuric acid. Heating to above 700 ℃ in air oxidizes to zirconia. 

Synthesis process: 

1. Direct nitriding method: Metal zirconium powder (80-120 mesh) is spiral transported to a sealed stainless steel rotary kiln reactor, ammonia gas is introduced and the temperature of the reactor is controlled between 500-1100 ℃. The nitriding reaction is carried out continuously, and the resulting zirconium nitride is in powder form with a purity of over 99.6%. This method is easy to obtain raw materials, stable in the process, suitable for continuous production, and environmentally friendly. 

2. Zirconium tetrachloride method: Zirconium tetrachloride reacts with ammonia to form an adduct, which is then heated to 750 ℃ to convert into zirconium nitride (Zr3N4), and further heated to 1200 ℃ to convert into zirconium nitride (ZrN). Zirconium nitride can also be synthesized by reacting in the presence of hydrogen at temperatures above 1000 ℃. 

Purpose: 

1. In the field of biology: 

Biosensors: Zirconium nitride has excellent electrical properties and biocompatibility, and can be used to manufacture biosensors for detecting biomolecules and cells. These sensors have wide applications in medical diagnosis, environmental monitoring, and biological research. 

Medical devices: Due to their excellent biocompatibility and chemical stability, zirconium nitride is used to manufacture artificial joints, dental implants, and bone repair materials. Its high hardness and wear resistance make medical devices have a longer service life and better performance. 

Implant material: Zirconium nitride can be used as an implant material, such as artificial joints and implant trays, which are compatible with human tissue and provide stable support. 

Cell culture matrix: The surface of zirconium nitride can be modified to support cell adhesion, making it suitable for cell culture and tissue engineering, especially performing well in high-temperature cell culture and heat disinfection. 

Bioceramic materials: Zirconium nitride is used to manufacture artificial bones and dental restoration materials, which are compatible with human tissues and provide stable support and repair functions. 

2. Industrial sector: 

High temperature resistant alloy material: Zirconium nitride has a very high melting point and decomposition temperature, good chemical stability, and is widely used as a high-temperature resistant alloy material for aerospace rocket engine injection ports, alloy materials for national defense artillery missiles, and corrosion-resistant materials for petrochemical reducing chloride reactors or containers. 

Superhard tool material: Zirconium nitride is suitable for superhard tool materials and surface protection materials due to its high hardness and wear resistance. 

Electric furnace lining material: It is also used in refractory and high-temperature resistant materials for the lining of ultra-high temperature electric furnaces. 

3. Other applications: 

High performance cutting tools: Nano zirconium nitride can be used to manufacture high-performance hard cutting tools, improving their wear resistance and service life. 

High temperature ceramic conductive materials: Due to their high temperature resistance and conductivity, zirconium nitride can be used for the preparation of high-temperature ceramic conductive materials.
