 Yes,you are right. Ionic compounds ,such as  NaCl and KCl, can also melt 
once the temperature reachs the melting point.  Their m.p. is generally  
very high .The melting point of NaCl is 1074K(CRC Handbook of Chemistry 
and Physics, the 66th edition,1985/86). In industry, the meltal Na is 
prepared from the electrlysis of the melted solution of NaCl.
