There is also a chance of getting a V materia by combinging 5 IV materia. I've gotten at least 10 V this way before there was Mhach.


Another use, thought I wouldn't recommend it with V materia is to increase spirit bond rate or desynthesis rate. Equipping any materia to any piece of gear will increase the spiritbond rate and increase chance of successful desynth as well. But, of course, grade I materia are preferable because they are so cheap.
So it doesn't have any actual use in battle? Why, SE, why...
