How does the presence of oxygen-containing groups on the surface of graphite (e.g., after oxidation) affect its behaviour in composite materials?
Which feature of graphite gives it a very high melting point?
Which property of graphite makes it useful as a material for high-temperature crucibles and refractory parts?
How does doping (adding small amounts of other elements) of graphite affect its electrical properties?
Which laboratory test would most directly show that a powdered sample contains graphite rather than diamond?
Graphite is used as a moderator (neutron absorber) in some nuclear reactors. Which property is most relevant to this use?
Why can graphite conduct electricity whereas diamond cannot?
Why is graphite considered chemically stable in many environments but can still be oxidised at high temperatures in air?
What causes the anisotropic (direction-dependent) properties of graphite, such as different electrical conductivity parallel and perpendicular to the layers?
What type of bonding holds each carbon atom to three neighbouring carbon atoms within a graphite layer?
Why does graphite conduct heat well along the layers?
