MgTiO3 vs TiO2 Ceramic

Ceramic · grade comparison

MgTiO3 and TiO2 Ceramic are both ceramic grades. TiO2 Ceramic is the stronger of the two: tensile strength 80 MPa (11.6 ksi) against 70 MPa (10.2 ksi) for MgTiO3, about 14% more. TiO2 Ceramic is harder — 950 HV against 700 HV for MgTiO3 — which matters for wear surfaces and threads. MgTiO3 is lighter (3.8 g/cm³ vs 4.15 g/cm³ for TiO2 Ceramic) and TiO2 Ceramic is stiffer (250 GPa vs 150 GPa).

MgTiO3 vs TiO2 Ceramic — frequently asked

Is TiO2 Ceramic stronger than MgTiO3?

Yes. TiO2 Ceramic has a typical tensile strength of 80 MPa (11.6 ksi) against 70 MPa (10.2 ksi) for MgTiO3 — about 14% more.

Which is cheaper, MgTiO3 or TiO2 Ceramic?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

When should I choose MgTiO3 over TiO2 Ceramic?

Pick MgTiO3 when weight is the constraint. Pick TiO2 Ceramic when strength drives the design, or when surface hardness matters.
