1. Good chemical stability, most chemical liquids does not react with it, thus will not be corroded by it.
2. Surface of inside and outside are smooth, easy to clean and small wear.
3. Little difference in particle size
4. high grinding efficiency
5. lower wear
6. Good sphericity and high specific gravity are beneficial to improve grinding efficiency
7. The surface gloss is high and the hardness is moderate, which can protect the equipment from wear and tear
