CVD Diamond Substrates (Chemical Vapor Deposition Diamond Substrates) are materials that use thin films of diamond manufactured using the Chemical Vapor Deposition (CVD) method as substrates. In the CVD method, diamond is grown on a substrate by a chemical reaction using a gaseous carbon source (usually methane). This process allows for the creation of high-quality diamond thin films.

Features of CVD Diamond Substrate:

High thermal conductivity

Diamond has higher thermal conductivity than metal, making it suitable for applications where thermal management is important.

Excellent hardness and wear resistance

As the hardest substance in nature, diamond is resistant to friction and wear, making it useful for cutting and grinding tools.

High electrical insulation

Diamond is an excellent insulator, making it useful for equipment and devices that require electrical properties.

High chemical stability

Diamond is chemically very stable, able to maintain its performance even under harsh conditions.

Transparency and optical properties

With its high transparency and ability to transmit a wide range of light from ultraviolet to infrared, it is also applicable to optical devices.

Main Applications:

• Diamond Cutting Tools
• For Wire Drawing Dies
• Optical Windows
• Thermal Management Applications (Heat Spreaders for Lasers, etc.)
• Dressing Tools
• Electronic Devices (High Frequency, High Voltage Devices)

It is possible to customize high-quality CVD single-crystal diamond products according to various sizes and specifications.
