What property of quartz makes it useful as an ingredient of sandpaper?

The mineral is hard compared to most of the objects it would be used to abrade. On the Mohs Scale of relative mineral hardness it's a seven with ten being the hardest. It is not widely used as an abrasive because quartz has a high silica content. Silica, in its natural form, is a potential health hazard (silicosis) when ingested through the lungs. Therefore, it is not frequently used as an abrasive in abrasive blasting applications.
