-Very high melting points
-Very high boiling points
-Don't conduct electricity when molten (except for graphite)
e.g. diamond, graphite and silicon dioxide
Diamond and graphite are alloptropes of carbon. This means they are both made of carbon, however the way they are arranged is different, therefore they have different properties (e.g. diamond is very hard and does not conduct electrcity, however graphite does).
