99.99% C Carbon Graphite Pellets Granules Evaporation Materials CAS NO.7440-44-0

High Hardness: Carbon, especially in its diamond-like form, is extremely hard and wear-resistant, making it suitable for protective coatings.

High Melting Point: Sublimation point of carbon is around 3,650°C, allowing its use in high-temperature deposition processes.

Good Electrical Conductivity: Carbon is conductive, making it suitable for electronic applications.

Chemically Inert: Carbon’s chemical stability ensures it remains durable in corrosive environments, enhancing the lifespan of coated materials.

Low Coefficient of Friction: Diamond-like carbon (DLC) films offer excellent lubricity and are used to reduce wear in mechanical systems.

Carbon (C) pellets are used as an evaporation material in physical vapor deposition (PVD) processes, such as thermal and electron-beam evaporation. Carbon thin films are valuable in various applications due to their electrical conductivity, hardness, and chemical inertness. Carbon coatings are often utilized in semiconductor devices, optical components, and protective coatings.

Application

1. Semiconductors: Carbon thin films are used in electronics for applications like conductive layers, resistors, and other carbon-based semiconductor devices.

2. Optical Coatings: Carbon coatings are used for anti-reflective and protective purposes in optical systems, particularly in infrared (IR) and ultraviolet (UV) applications.

3. Protective Coatings: Carbon’s hardness and wear resistance make it an ideal candidate for protective coatings in mechanical parts and tools.

4. Biomedical Applications: Diamond-like carbon (DLC) films are used in medical devices due to their biocompatibility and high wear resistance.
