1. Basic Information
Name: Carbon
Alias: Carbon powder, activated carbon, graphite, carbon black
CAS No.: 7440-44-0
Molecular Formula: C1
Molecular Weight: 12.01
2. Physical and Chemical Properties
Physical Properties
- Appearance: Black solid, diverse forms: amorphous carbon powder, graphite flake, diamond granular, porous activated carbon
- Odor: Odorless
- Solubility: Insoluble in water, all organic solvents, acids and alkalis under normal temperature
- Melting/Sublimation: Sublimes at ~3652 °C under normal pressure
- Density: Graphite 2.25 g/cm3; amorphous carbon 1.8–2.1 g/cm3; diamond 3.51 g/cm3
- Hygroscopicity: Porous activated carbon has strong adsorption and moisture absorption capacity; dense graphite/diamond non-hygroscopic
Chemical Properties
- Molecular Structure: Elemental carbon with multiple allotropes (graphite, diamond, carbon nanotube, graphene, amorphous carbon)
- Combustion performance: Burns fully in sufficient oxygen to produce CO2; incomplete combustion generates CO; does not burn in air below 350 °C
- Reduction property: High-temperature reducing agent, reduces metal oxides to crude metals (iron smelting, copper refining)
- Adsorption characteristic: Porous carbon materials have huge specific surface area, adsorb organic matter, pigment, odor, heavy metal ions
- Acid-base stability: Chemically inert at room temperature, resistant to most acids and alkalis; reacts with strong oxidants (concentrated nitric acid, concentrated sulfuric acid) under heating
- Photostability: Stable to light, no discoloration or decomposition
3. Main Application Fields
1. Industrial Adsorbent & Purification Material (Core Application)
- Activated carbon for water treatment, waste gas deodorization, solvent recovery, food decolorization
- Carbon black as reinforcing filler for rubber tires, plastic colorant, ink/pigment raw material
2. Metallurgical & Thermal Industry
Coke as fuel and reducing agent for ironmaking and steelmaking; graphite electrode for electric arc furnace smelting
3. New Energy & Electronic Materials
- Graphite negative electrode material for lithium-ion batteries; conductive carbon black for supercapacitors
- Graphene/carbon nanotube conductive additives for electronic devices and heat dissipation materials
4. Daily Chemical, Food & Medical Auxiliaries
Food-grade activated carbon for sugar, wine decolorization; medicinal carbon for gastrointestinal toxin adsorption; pencil lead, lubricating graphite powder

Safety Warning
Black dust easily floats and irritates eyes, nose and respiratory tract; long-term inhalation may cause lung dust deposition. Wear dust mask and goggles during operation, keep ventilation. Finely divided carbon powder is combustible dust, far away from open fire, static electricity and strong oxidants to prevent dust explosion. Waste carbon can be recycled or incinerated harmlessly.
