Cost comparison of Zirconia vs Alumina screws

Q: Why does Zirconia cost more than Alumina?

A:  1) Raw material cost: Aluminia is far more abundant, whereas Yttrium oxide which is a stabilizer for Zirconia ceramic, is a rare earth element.

2) Shaping costs: Due to its higher density it takes approximately 10x longer to grind down and shape Zirconia into parts.

3) Higher sintering temperatures:  The thermal shock resistance for Zirconia is poor so it requires a more costly sintering process.
