Please suggest me the acid or solution for complete digestion of Rutile (TiO2), Silica (SiO2), Fluorospar(Caf2) ceramic materials?

09 May 2017 1 8K Report

I have dissolved all these minerals in 5ml HF+HNo3 but TiO2 remain undissolved even in Microwave heating at 200 deg.cel.

So plz suggest me the acid/solution for complete dissolution of above minerals specially TiO2.

Carlos Araújo Queiroz

CaF2 dissolves (slowly) in nitric acid. Concerning to (reactively) dissolving TiO2, please check: https://www.researchgate.net/post/Does_anyone_know_how_to_etch_the_Titanium_dioxide_TiO2_from_surface_of_a_glass2 https://www.researchgate.net/post/Can_anyone_help_with_a_wet_etchant_for_TiO2_nanoparticles
