Core Characteristics of Diamond
Diamond is a crystalline form of carbon and an allotrope of carbon, like graphite. Its chemical composition is almost pure carbon, containing only trace amounts of nitrogen impurities (about 0.01–0.25%). Pure diamond is transparent and colorless; however, due to impurities or lattice defects, it may appear in various shades such as pale yellow, blue, or green. Generally, natural diamonds are often pale yellow, while synthetic diamonds frequently exhibit a yellow-green appearance.
In terms of physical properties, diamond possesses:
- The highest hardness of any known material (Mohs hardness of 10), with a density of approximately 3.515 g/cm³.
- Extremely high thermal conductivity (approx. 2200–2600 W/m·K).
- Excellent electrical insulation and chemical stability. Its surface is hydrophobic and lipophilic, extremely inert at room temperature, and resistant to corrosion by general chemical reagents.
Under oxidizing conditions, diamond stability varies with the environment: above 600°C in pure oxygen, the surface gradually loses luster and blackens; combustion begins between 700–800°C. The oxidation onset temperature for synthetic diamonds is approximately 740–840°C, with combustion temperatures falling between 850–1000°C.
With its **extreme hardness, excellent thermal conductivity, optical transparency, and high sound velocity propagation**, diamond can operate stably in extreme high-temperature, high-pressure, and highly corrosive environments, making it the ideal choice for **high-precision machining, thermal management components, and advanced semiconductor materials**.
Diamond Thermal Conductivity Mechanism and Electronic Application Potential
Diamond’s heat conduction relies mainly on the **phonon transfer mechanism**. Due to its tight lattice, strong covalent bonds, and minimal defects, phonons can propagate at high speeds with little scattering, forming excellent thermal conduction channels.
In high-power chips, reliability drops by about 10% for every 1°C rise in temperature.
Diamond substrates effectively disperse heat, suppress hotspots, and enhance system stability, making them the core material for next-generation power chips and high-efficiency cooling solutions.
Industrial Applications of Diamond
1. Precision Cutting and Ultra-Mirror Polishing
Diamond abrasives, with their unrivaled hardness, are the top choice for processing various super-hard and brittle materials. This application field spans traditional manufacturing, precision optics, and medicine, ensuring products meet the highest standards of geometric precision and surface finish.
- Traditional Industry and Molds: Precision grinding, polishing, and sharpening of hard alloys (e.g., Tungsten Carbide), ceramics, and mold steels.
- Precision Optics and Chemistry: Fine grinding and polishing of sapphire substrates, optical glass, quartz, and fiber optic ends, as well as chemical instrument applications like diamond electrodes and diamond-coated tools.
- Medical and Structural Ceramics: Precision forming of biomaterials like bio-ceramics, high-strength ceramic dentures, and artificial joints.
