What are Industrial Diamonds?
Industrial diamonds, also known as artificial diamonds or synthetic diamonds, are diamonds manufactured in an industrial process, as opposed to natural diamonds, which are created over periods ranging from 1 billion to 3.3 billion years inside the Earth's mantle. Unlike gem-quality diamonds which are used in the jewelry industry, industrial diamonds are valued mostly for their mechanical properties such as hardness, thermal conductivity, and chemical resistance.
Characteristics of Industrial Diamonds
Industrial Diamond are generally composed of diamond crystals that average 0.5 to 1 mm in size. Most industrial diamonds have a hardness rating of 10 on the Mohs hardness scale, the highest and hardest level attainable. Their crystalline structure and covalent bonds between carbon atoms impart excellent physical and chemical properties that make industrial diamonds useful for a variety of demanding industrial applications. Some key characteristics of industrial diamonds include:
- Hardness: Industrial diamonds are essentially the hardest known natural material. Their extreme hardness enables them to hold precision edges and help shape other very hard materials without wearing down themselves.
- Heat Conductivity: Diamonds are exceptional conductors of heat, even more so than copper. They can effectively remove heat from grinding and cutting processes.
- Chemical Resistance: Due to their strong carbon bonds, industrial diamonds do not chemically react with most materials at normal temperatures. They maintain sharp cutting edges in harsh and corrosive industrial environments.
- Low Friction: When used in applications involving sliding abrasion against itself or other materials, diamond possesses an extremely low coefficient of friction.
- Transparency: Some types of industrial diamonds, such as single-crystal diamond, readily transmit light beams in the ultraviolet, visible and infrared regions of the electromagnetic spectrum.
Uses and Applications of Industrial Diamonds
Given their unmatched mechanical properties, industrial diamonds find applications where conventional materials cannot perform or fail prematurely. Some of the major uses of industrial diamonds include:
- Abrasive Products - Industrial diamonds used in abrasive products such as cutting and grinding wheels, blades, drills and saws are the workhorses of machining, construction and other industries. They shape materials ranging from granite to super-hard metal alloys.
- Heat Sinks - Single-crystal diamond heat spreaders effectively transfer heat generated by high-power electronics and laser systems. They help prevent overheating and component failure.
- Diamond-Like Carbon Coatings - Nanocrystalline diamond coatings provide ultra-hard, anti-friction and anti-corrosion surfaces for mechanical components, high-precision instruments and medical implants.
- Optics - Diamonds' strength and transparency properties make them suitable for industrial applications such as windows for high-power CO2 lasers and infrared optical components.
- Electronics - Electronic-grade diamonds are used in high-frequency microwave devices and sensors due to their exceptional thermal conductivity and electrical insulation properties.
