  2. Carbon black - Wikipedia

    en.wikipedia.org/wiki/Carbon_black

    Carbon black (with subtypes acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking in a limited supply of air.

  3. Electroconductive carbon black - Wikipedia

    en.wikipedia.org/wiki/Electroconductive_carbon_black

    Carbon black particle size is between 10 and 100 nm, while the surface particle size is between 20 and 1,500 m 2 /g. Generally speaking, small carbon black particles with a high surface area are darker, have higher viscosity and lower wettability, are harder to disperse, retain greater conductivity and absorb UV radiation well.

  4. Black oxide - Wikipedia

    en.wikipedia.org/wiki/Black_oxide

    The solution can be used on cast iron and mild low-carbon steel. The resulting finish complies with military specification MIL-DTL–13924D Class 4 and offers abrasion resistance. Black oxide finish is used on surgical instruments in light-intensive environments to reduce eye fatigue. [citation needed]

  5. Coal tar - Wikipedia
