Overview of XXX

Zirconium Carbide (ZrC) is an extremely hard and refractory ceramic material composed of zirconium and carbon atoms. It belongs to the family of transition metal carbides, known for their high melting points, exceptional hardness, and impressive chemical stability. Zirconium carbide offers unique properties that make it suitable for demanding environments where high temperatures, wear resistance, and corrosion are significant concerns.

Features of ZrC CAS 12070-14-3 Powder Zirconium Carbide

  1. High Melting Point: Zirconium carbide has an incredibly high melting point of approximately 3530°C, making it one of the most heat-resistant materials.

  2. Exceptional Hardness: With a Vickers hardness rating around 2200 Hv, ZrC is harder than most steels and many other ceramic materials, providing excellent wear resistance.

  3. Oxidation Resistance: Forms a protective oxide layer when exposed to oxygen, which prevents further oxidation, enhancing its high-temperature performance.

  4. Chemical Stability: Resistant to most acids, except for hydrofluoric acid, and shows excellent resistance to corrosion from alkalis and salt solutions.

  5. Thermal Conductivity: Exhibits good thermal conductivity, which aids in heat dissipation and is beneficial for applications involving high heat loads.

  6. Nuclear Application Suitability: Zirconium carbide’s low neutron absorption cross-section makes it attractive for use in nuclear reactor components.

Parameters of ZrC CAS 12070-14-3 Powder Zirconium Carbide

The “CAS” (Chemical Structure Symbol) number for ZrC, also known as Zirconium carbide, is 12070. This chemical formula represents the general formula of zirconia: [XZr(CO)2], where X represents a metal atom or ion and Z represents an element. The atomic mass of zirconia is 95.96 g/mol, so its atomic number is 40.

The parameter for ZrC, called the “Cas” number, provides information about the physical properties of the material, including its hardness, melting point, thermal stability, and other relevant parameters. It’s important to note that this Cas number is not specific to ZrC but applies to all types of zirconia materials, regardless of their composition.

FAQs of ZrC CAS 12070-14-3 Powder Zirconium Carbide

Q: How is ZrC CAS 12070-14-3 Powder Zirconium Carbide produced?
A: ZrC CAS 12070-14-3 Powder Zirconium Carbide is typically synthesized through carbothermal reduction of zirconium dioxide (ZrO2) with carbon at very high temperatures.

Q: Is ZrC CAS 12070-14-3 Powder Zirconium Carbide biocompatible?
A: While zirconium itself has good biocompatibility, specific studies are needed to determine the biocompatibility of zirconium carbide for medical applications.

Q: How does ZrC CAS 12070-14-3 Powder Zirconium Carbide compare to tungsten carbide in terms of hardness and thermal properties?
A: Tungsten carbide (WC) is slightly harder than zirconium carbide and has a higher melting point, making WC more commonly used for applications requiring extreme hardness and heat resistance.

Q: Can ZrC CAS 12070-14-3 Powder Zirconium Carbide be machined or shaped easily?
A: Due to its extreme hardness, zirconium carbide is challenging to machine using conventional methods. It is typically formed through powder metallurgy techniques, sintering, or used as a coating applied by thermal spray or CVD/PECVD processes.

Q: What is the main advantage of using ZrC CAS 12070-14-3 Powder Zirconium Carbide in nuclear applications?
A: Its low neutron absorption cross-section and high-temperature stability make it an ideal material for components in nuclear reactors, minimizing interference with nuclear reactions while maintaining integrity under extreme conditions.
