TaC-coated Graphite Description
TaC-coated Graphite refers to high-purity isotropic graphite materials that have been coated or treated with a layer of dense tantalum carbide via CVD. Tantalum carbide is a hard, refractory ceramic compound composed of tantalum and carbon. Coating graphite with TaC can enhance the properties and performance of the graphite in various high-temperature and abrasive environments.

TaC-coated Graphite Applications
1. Furnace Insulation: TaC-coated graphite can be used in furnace insulation and hot zones, where it provides excellent thermal stability and resistance to high temperatures.
2. Wafer Handling: In semiconductor fabrication, TaC-coated graphite can be used in components like wafer-handling tools, susceptors, and crucibles for processes involving high temperature, chemical vapor deposition, and epitaxial growth.
3. Aerospace and Defense: C-coated graphite is used in the manufacturing of rocket nozzles and heat shields.
4. Metallurgy: TaC-coated graphite crucibles are used in the melting and casting of metals like steel and superalloys.
5. Chemical Process Equipment: TaC-coated graphite can be employed in components of chemical processing equipment that are exposed to high temperatures and corrosive chemicals.
6. Abrasion-Resistant Applications:
· Mechanical Seals: TaC-coated graphite is used in mechanical seals where both lubricity and abrasion resistance are required to prevent leakage in rotating equipment.
· Bearings: In applications that demand abrasion resistance, such as high-speed rotating machinery, TaC-coated graphite can be used in bearings to reduce friction and wear.
7. Nuclear Fuel Manufacturing: TaC-coated graphite may be used in nuclear fuel manufacturing processes, where it can handle the high temperatures and radiation encountered.
