Would a dilute or a concentrated sodium fluoride solution have a higher boiling point? Why?

I think it would depend on what the dilute was, the boiling point of sodium fluoride is 1700 degrees C, or 3092 F. So if you dilute it with water which has a boiling point of 100 degrees C. or 212 F, it seems to me that any amount of water would lower the boiling point of the sodium fluoride.
Don't take this as fact, if is just one mans opinion.
