I have titanium powder , can i deposit it on glass substrate via thermal deposition ????
My basic need is to first deposit the Ti then aneal it to change into titanium dioxide .
Dear Yogesh Singh
Yes, you can. Please read the following articles for further details:
Article Thermal Atomic Layer Deposition of Titanium Films Using Tita...
Article Deposition by thermal evaporation of thin films of titanium ...
You can deposit TiO2 film directly by thermal evaporation process using TiO2 powder and you have to use tungsten boat or basket for evaporation.
Dear Yogesh Singh as Gourab Das says you can deposit Ti by thermal evaporation, but it is a tricky thing, at least in my experience with an old thermal evaporator (Balzers 250). Even at the maximum vacuum achievable the evaporation temperature for Ti was close to the limit of the machine.
If your goal is to achieve a layer of TiO2, you can add O2 during the evaporation process and oxidation will run directly.
Hope it helps.
Dear Yogesh Singh you can also deposit TiO2 film as suggested by Manuel Gómez but you have to optimize the O2 flow according to your need.
Gourab Das ca i deposit tio2 from thermal ??? really ! is it possible ??? once I tried to deposit Sn O 2 but it was not depositing . What should I do ????
Dear Yogesh Singh
Indeed you can do it, however the thickness of the titanium layer obtained by thermal evaporation does not exceed 500 A ° (1). On the other hand, deposits with more interesting thiknesses were obtained by "electron-beam evaporation" (2) or "magnetron sputtered coating" (3).
