This is very different from ionic or covalent bonds, where electrons are held by one or two atoms. The metallic bond is therefore strong and uniform. Since electrons are attracted to many atoms, they have considerable mobility that allows for the good heat and electrical conductivity seen in metals.

The Quartz Page: Physical Properties
The thermal conductivity of quartz is higher than that of glass, so overall it can take a bit more [9], but it's still better to handle quartz crystals with care. In general, quartz feels colder than glass. The thermal conductivity is anisotropic and higher parallel to the c-axis.

GCSE CHEMISTRY - Titanium - Extraction - Rutile - Titanium ...
Titanium ore is called rutile. Rutile contains titanium dioxide - TiO 2. Titanium dioxide is converted into titanium chloride - TiCl 4. Titanium is more reactive than carbon but it is not extracted by electrolysis because titanium chloride is covalent and therefore does not conduct electricity. Titanium chloride is a yellow liquid (melting ...
