How to prevent titanium from oxidation?

Question

we mix Titanium (Ti ) Powders with TiO2 in water to make a slurry or use mortar to grind. After complete mixing Titanium is Changed to TiO2 before printing (experiment). Is there any liquid or other mixing methods which can stop the reaction (oxidation) of Titanium?

Answer 1

Titanium in air forms a very thin oxide layer, but the bulk of the Ti is still not oxidized.  To my knowledge, this cannot be prevented. However, when in solution, one can prevent or greatly diminish further oxidation by the inclusion of an acid (HCl, H2SO4, etc.).

If you want to try to prevent oxidation in air, you could possible use an inert gas atmosphere. But unless the Ti originally comes in such an environment, it will already passivate, and you'd have the thin layer of oxide.
