Carbon

Carbon is a chemical element with the symbol C and atomic number 6. It is a nonmetal and is tetravalent—meaning carbon atoms can form four chemical bonds with other atoms. It is the 15th most abundant element in the Earth's crust, and is essential for all known life forms.

Material Properties

• Allotropes: Carbon exists in numerous allotropic forms with significantly different properties. The most well-known include:
  • Diamond: Exceptionally hard, transparent, excellent thermal conductor, electrical insulator.
  • Graphite: Soft, black, slippery, good electrical conductor, used as a lubricant and in pencils.
  • Fullerenes: Spherical or tubular molecules (e.g., buckminsterfullerene - C60), with unique properties.
  • Carbon Nanotubes: Cylindrical structures with high strength and electrical conductivity.
  • Graphene: A single layer of carbon atoms arranged in a hexagonal lattice, extremely strong, flexible, and conductive.
  • Amorphous Carbon: Lacks a long-range order, found in materials like charcoal, soot, and coal.
• Hardness: Varies greatly depending on the allotrope (diamond being the hardest known natural material).
• Density: Ranges from 1.02 g/cm³ (graphite) to 3.51 g/cm³ (diamond).
• Melting Point: Sublimes at around 3,652 °C (graphite). Diamond has a higher melting point, though it is difficult to determine precisely.
• Chemical Reactivity: Forms stable covalent bonds with many elements, including hydrogen, oxygen, nitrogen, and other carbon atoms.

Purpose & Function

• Basis of Organic Chemistry: Carbon's ability to form long chains and complex structures makes it the fundamental element in organic chemistry and the backbone of all known life.
• Energy Source: Fossil fuels (coal, petroleum, natural gas) are primarily composed of carbon compounds and are major energy sources.
• Structural Component: Used in construction materials, composites, and manufacturing due to its strength and versatility.
• Lubricant: Graphite is used as a dry lubricant in various applications.
• Electronics: Carbon materials like graphene and carbon nanotubes are used in advanced electronic devices.
• Filtration and Absorption: Activated carbon is used in filters for purifying water, air, and other substances.

Usage Scenarios

• Jewelry: Diamond is prized for its beauty and durability.
• Cutting Tools: Diamond-tipped tools are used for cutting and grinding hard materials.
• Pencils: Graphite is the core material in pencil leads.
• Batteries: Carbon materials are used in battery electrodes.
• Automotive Industry: Carbon fiber composites are used to reduce weight and improve performance.
• Aerospace Industry: Carbon fiber composites are used in aircraft structures.
• Water Purification: Activated carbon filters remove contaminants from water.
• Air Filtration: Activated carbon filters remove odors and pollutants from air.
• Medical Applications: Carbon materials are used in drug delivery systems and medical implants.
• Steel Production: Carbon is used in the steelmaking process.
