What Metal is a Good Conductor of Heat
In general, metals are shiny, reflecting most of the light that strikes them. They are malleable and ductile (that is, they will bend under pressure and are not brittle). They have a broad range of melting temperatures (e.g., mercury is a liquid at room temperature
Why does SiC have a high melting point?Why is its …
Silicon Carbide (industrially known as Carborundum) is extremely rare in nature, but has been produced in quantity since the 1890''s. Its hardness has found many uses in industry; diamond jewelry
GIANT COVALENT STRUCTURES - chemguide
27/1/2019· Note: The logic of this is that a piece of graphite ought only to conduct electricity in 2-dimensions because electrons can only move around in the sheets - and not from one sheet to its neighbours. In practice, a real piece of graphite isn''t a perfect crystal, but a host of small crystals stuck together at all sorts of angles.
