Zirconium Carbide

Zirconium Carbide granules is a kind of black or gray particles with the chemical formula of ZrC, with high melting point and high hardness, good chemical stability, excellent electrical conductivity and thermal conductivity, low density and high strength, and other physicochemical properties, which has important applications in the field of ultra-high temperature structural materials, cutting tools, electronic devices, ceramic-based composites and other fields.

Characteristics

Chemical formula: ZrC

Molecular weight: 103.23

CAS No.: 12070-14-3

Appearance: usually black or gray granular

High melting point and high hardness: Zirconium carbide has a very high melting point of about 3540°C, which enables it to maintain stable physical and chemical properties at ultra-high temperatures, showing excellent high-temperature resistance. Its hardness is also quite high, second only to diamond and a few other super-hard materials, with excellent wear resistance, and can effectively resist abrasion and scratches.

Good chemical stability: At room temperature, zirconium carbide is highly resistant to most acids, alkalis, salts and other chemicals, and is not prone 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.

Excellent electrical and thermal conductivity: zirconium carbide has good electrical conductivity, and the electrons in its crystal structure can move more freely, making it potentially valuable in the field of electricity. 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.

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 has high strength. This combination of low density and high strength gives it a significant advantage in aerospace, automotive and other fields that require both lightweight and high performance materials.

Applications

Ultra-high-temperature structural materials: Due to its excellent high-temperature resistance, high strength and chemical stability, zirconium carbide particles are often used in the manufacture of ultra-high-temperature structural parts such as hot-end parts of aerospace engines, rocket nozzles, etc., which are able to withstand extreme high temperatures and complex mechanical environments to ensure reliable operation of aircraft under high-temperature conditions.

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

Electronic devices and functional materials: With its good electrical and thermal conductivity, zirconium carbide particles can be used to prepare electrodes, heat generating elements, heat dissipation parts 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., which plays an important role in the fields of electronic information and energy.

Ceramic matrix composites: Zirconium carbide particles are added to the ceramic matrix as a reinforcing phase, which can significantly improve the strength, toughness and abrasion resistance of ceramic materials, and prepare high-performance ceramic matrix composites. This kind of composite material has a broad application prospect in ceramic engine, ceramic armor, chemical corrosion-resistant equipment and so on.
