yes, but not in the solid state
Yes, ionic compounds can only conduct electricity when molten or dissolved.
a molten one
Almost all molten covalent compounds are much worseconductors than almost any molten ionic compounds. However, note that some ionic compounds contain covalently bonded polyatomic ions, and many of these can conduct electricity as well as most other ions in a melt.
Ionic compounds conduct the electricity when their ions move freely that means in molten state or in aqueous solution.
Even insoluble ionic compounds such as CaCO 3 are electrolytes because they can conduct a current in the molten (melted) state.

A compound that does not conduct an electric current in aqueous solution or in molten state is a covalently bonded compound. It could also be called a "non-ionogen".

These compounds are called electrolytes.
As there are no free electrons to carry the electric current, hydrocarbons cannot conduct electricity (whether molten or not).

When sodium chloride is melted, the orderly crystal structure breaks down. If a voltage is applied across this molten mass, cations migrate freely to one electrode and anions migrate to the other. This movement of ions allows electric current to flow between the electrodes through an external wire. For a similar reason, ionic compounds also conduct electric current if they are dissolved in water. When dissolved, the ions are free to move about in the solution.
When molten the ions can move under the influence of trhe electric firld. in the solid they are held in a lattice and movement is more difficult. Note there are special ionci compoundscaled fast ion conductors where the ions do move faitly freely - compounds like this are found in modern batteries.

You can separate chlorine from common table salt by running an electric current through molten sodium chloride, which has a melting point of 801°C.
