Introduce:
Zirconia's high density, low porosity, inertness, toughness and super hardness make it the perfect material for making mortars and pestles. Being approximately 10 on the Mohs hardness scale, zirconia mortar and pestles is able to grind materials too hard for agate, alumnia, and porcelain. Our high wear-resistant mortar and pestle effectively eliminates product contamination and is chemically inert to all acids. These special features make zirconia the most versatile and best suited mortar and pestle material for sensitive biological and other critical applications requiring ultra-low contamination and acid resistence.

Zirconia (YSZ) Grinding Applications
1. Hard Materials
Zirconia's superior hardness allows it to grind tough ceramics such as aluminum oxide and silicon oxide.
2. Low Contamination Materials
When absolutely no contamination is tolerable, such as in ultra-pure organic, nanomaterial, and forensic applications, Zirconia is your best choice.
3. HF Applications
Zirconia's inertness to HF and other acids make it superior to Agate and other materials.
4. High Temperature Applications
Zirconia's physical and thermal shock resistance lend it well to high temperature applications.
