Zirconia liners offer lifetime cost savings, significantly longer service, better performance and safer operation than these made of more commonly used alumina ceramic.

1. Zirconia exhibits better impact strength

2. Zirconia is harder than alumina. Hardness is HV 0.3 kg/mm - 1100/1200 (92-94Rc)

3. Zirconia can be honed to finer surfaces than alumina

4. Three to four times finer than alumina.
