This document discusses the preparation, physical properties, chemical properties, uses, and interesting facts about fullerene and lamp black. Fullerene is made by heating graphite with inert gases and separates into different types using chromatography. It is a black powder that dissolves in benzene and is thermally stable. Lamp black is a soft black pigment produced from imperfect combustion of coal tar oils and is not a good conductor of electricity or heat. Uses of fullerene include cancer therapy and lubricant additives, while lamp black has been used as a pigment and coating.

1. Fullerene
and
Lamp black

2. Preparation
Lamp Black Fullerene
1)Lamp black is procured by the imperfect
combustion of oils obtained in coal-tar
distillation.
2)A very fluffy and light powder is derived
by collecting the soot from the burning oil.
1)Fullerenes are made by heating of
graphite in an electric are in the
presence of inert gases such as helium
or argan .
2) The different fullerenes are then separated
by chromatography.

3. Physical properties
● Fullerene is a black powdery material.
● It forms deep magenta solution, when dissolved in
benzene.
● It is very tough and thermally stable.
● It exists as a discrete molecule, unlike the other two
allotropes of carbon (diamond and graphite).
● It can be compressed to lose 30% of its volume
without destroying its carbon cage structure.
● Lamp black is a soft brownish or
bluish-black pigment.
● Refractive index is opaque.
● Possess a low degree of crystallinity.

4. Chemical properties
1]Lampblack is NOT a good conductor of heat or electricity.
2]Fullerene is a good conductor of electricity
and heat.
3]There are extremely weak forces of attraction between the
molecules of buckminsterfullerene.

5. Uses
FULLERENE
- It is used in Cancer and AIDS Therapy
- it is used to increase the Antiwear and Antifriction properties of Lubricating oil.
LAMP BLACK
-Lamp black was commonly used in Egyptian tombs and murals as an alternative
to charcoal.
-it is also suitable as a pigment for heat-molded plastics, car fenders, coating for
electric wires and other products.

6. Fullerene are in fact carbon allotropes of carbon. They can
form hollow sphere, ellipsoid, tube and many other shapes.
U V inside the lamp is a source of radiation but won’t harm
your eyes or skin.
