1.	Besides man-made diamonds, among the frequently used sands it is the hardest and sharpest.
2.	The cutting rate is higher than that of aluminum oxide and emery; frequently used in cutting and carving.
3.	In comparison, higher wearing for blasting tubes and nozzles.

1.	Cleaning of very hard surfaces such as tungsten carbide.
2.	Used in deeper blasting and carving such as stone carving.
3.	With the ultrasound vibrating drilling machine, used in drilling of tiny holes.
4.	Used for blasting and cutting of thin and crisp workpieces
