Silicon - Infogalactic: the planetary knowledge core

Silicon is a solid at room temperature, with relatively high melting and boiling points of 1414 and 3265 C, respectively. Like water, it has a greater density in a liquid state than in a solid state, and so, like water but unlike most substances, it does not contract when it freezes, but expands.

Covalent Crystals | Introduction to Chemistry

Tungsten carbide (WC) is probably the most widely encountered covalent solid, owing to its use in carbide cutting tools and as the material used to make the rotating balls in ball-point pens. It has a high melting point (2870 °C) and a structure similar to that of diamond, although it is slightly less hard.
