No. Diamond is the hardest mineral. It measures 10 on the Mohs scale: Corundum measures 9, which is less hard than diamond, as below.

On mohs' hardness scale what mineral is harder than quartz but harder than appetite?

If you mean isn't harder than quartz but harder than apatite ( you spelled it wrong), that would be Orthoclase Feldspar. Else the minerals that are harder than both apatite and quartz are topaz, corundum, and diamond (diamond being the hardest, well the hardest non synthetic mineral).

Which is more strong diamond or carborandom?

Diamond, with a hardness rating of 10 on the Mohs scale, is harder than corundum (ruby and sapphire), which has a hardness rating of 9. However, diamond has perfect cleavage while corundum has no cleavage. So an answer to the original question would depend on the meaning of "strong."

Why would you use garnet to make sandpaper?

Sandpaper is made with corundum because it is extremely hard (9 on the Moh's Scale of Hardness) compared to just about anything else, except diamond (which top the scale at 10). This "hardness" is basically the factor which determines what happens when scraped against another material. If the corundum in the sandpaper is harder than whatever you are rubbing it against, then it will scratch the surface. If the sandpaper is used on something harder than corundum, the sandpaper will not be able to leave abrasions. Corundum is used because there are very few materials which it will fail to scratch.
