we are trying to get titanium dioxide into the air using a jet nebulizer for libs research and was hoping some one already figured out the best way to get the particles into the air.
Once I was synthesizing TiO2 from TiCl4 at lab scale, during experiment, I found out that whenever you spray TiCl4 in air, it ll readily be converted into TiO2, so try using TiCl4 and spray it, you shall get the particles.
The above experiment was accidental, I never tried this method, it was just my observation of that accident...:)
