Relatively high (771°C). As the previous poster indicated, it is an ionic salt, so the MP will be pretty darned high.
The melting point is a characteristic property of the chemical, so it doesn't change.
771° is pretty high, so it can't be relatively low.
And since it has a melting point, it must be able to melt.

Relatively high, because it's an ionic compound, with strong attractive forces between the oppositely-charged ions.
