Properties

Chemical formula: ZrC

Molecular weight: 103.23

CAS No.: 12070-14-3

Appearance: Usually black powder

High melting point and high hardness: Zirconium carbide powder has a very high melting point of about 3540℃, which enables it to maintain stable physical and chemical properties under ultra-high temperature environment, showing excellent high temperature resistance. Its hardness is also quite high, second only to diamond and a few other super-hard materials, with excellent abrasion resistance, which can effectively resist abrasion and scratches, and therefore performs well in applications requiring high hardness and abrasion resistance.

Good chemical stability: At room temperature, zirconium carbide is highly resistant to most acids, alkalis, salts and other chemicals, and is not susceptible to chemical reactions. Even at high temperatures, it has good resistance to some oxidizing atmospheres, and is able to maintain the stability of its structure and performance in harsh chemical environments, thus prolonging its service life and making it suitable for a variety of complex chemical environments.

Excellent electrical and thermal conductivity: the powder has good electrical conductivity, the electrons in its crystal structure can move more freely, making it a potential application in the field of electricity, can be used to manufacture parts that require electrical conductivity. At the same time, it also has excellent thermal conductivity, can quickly transfer heat, which is particularly important for applications that require efficient heat dissipation, such as high-temperature electronic devices, to help improve the performance and stability of equipment.

Low density and high strength: Compared with some traditional metal materials, zirconium carbide has a relatively low density of about 6.73 g/cm³ but high strength. This combination of low density and high strength gives it a significant advantage in aerospace and automotive applications that require both lightweight and high performance materials, which reduces the weight of the components while ensuring their strength and reliability.

Application

Ultra-high temperature materials: Due to its excellent high temperature resistance, high strength and chemical stability, zirconium carbide powder is often used in the manufacture of ultra-high temperature structural parts such as hot end parts of aerospace engines and rocket nozzles, which can withstand extreme high temperatures and complex mechanical environments to ensure the reliable operation of aircraft at high temperatures, which is of great significance in improving the performance and safety of aerospace equipment.

Wear-resistant materials: The high hardness of zirconium carbide makes it an ideal material for the manufacture of wear-resistant tools such as high-performance cutting tools, drills and grinding tools. Tools with zirconium carbide powder added have higher wear resistance and cutting performance, which can improve machining efficiency and machining precision, extend the service life of tools, and are widely used in machining, mining and other fields, reducing production costs and resource consumption.

Electronic devices: With its good electrical and thermal conductivity, zirconium carbide powder can be used to prepare electrodes, heating elements, heat dissipation components in electronic devices. In addition, it can also be used as an important functional material for the manufacture of high-temperature semiconductor devices, field emission materials, etc. It plays an important role in the fields of electronic information and energy, and helps to promote the technological development and innovation in related fields.

Ceramic matrix composites: adding zirconium carbide powder as a reinforcing phase to the ceramic matrix can significantly improve the strength, toughness and wear resistance of ceramic materials, and prepare high-performance ceramic matrix composites. Such composites have broad application prospects in ceramic engines, ceramic armor, chemical corrosion-resistant equipment, etc., and can meet the demand for high-performance materials in different fields.
