Arw Posted August 3, 2021 Posted August 3, 2021 I try to make smokeless/odorless/indoor fountainI think and search and read and test and did this thousand time with different material and not workedso I suspect to my titaniumThen bought a Chinese fountain and separate titanium and use this to my fountainand its worked!!I bought two different titanium from two different sellerI know that titanium dosen't react with acids but what I bought react and makes deep purple solutioninteresting part is this fake titanium burn like titanium in flame and make little crackleWhat can it be?
LiamPyro Posted August 6, 2021 Posted August 6, 2021 Purple? What kind of acid were you using? The only chemicals that come to mind are cobalt and potassium permanganate, which isnt very helpful. Could be that the titanium in the fountain and the titanium that you bought have different particle shapes, which is affecting how it behaves in a pyro composition. Might try looking at it under a microscope if you have access to one.

Mumbles Posted August 6, 2021 Posted August 6, 2021 Titanium can dissolve in HCl to generate a purple solution. Generally it's very slow, or requires heating. The purple is generally thought to be a Titanium (III) species. You need to do it in at least a partially sealed container to keep oxygen to a minimum, as it will eventually oxidize it back to a colorless or nearly colorless Ti(IV) state.
justvisiting Posted August 8, 2021 Posted August 8, 2021 Just out of curiosity, I took some -80 mesh Ti sponge that was known to be good and checked it out. 1/4 teaspoon was mixed with about a half ounce of straight muriatic acid. This is the commonly available hydrochloric acid, used for etching. Bubbles were slowly evolved at first, and no color. I went out for a couple of hours and came back to a very dark purple solution, with almost all the Ti dissolved. I did it outdoors.

That's rightI add some nitric acid and its become colorlessbut two pointthat was worm H2SO4(around30%) not HCland its react fast and make hydrogen gas by a lot of bubble but chinese one not make bubble and react toooooo slowand the most important part is why my Ti dose not worked and chinese did?

FlaMtnBkr Posted September 12, 2021 Posted September 12, 2021 (edited) What mesh size is it? Could it be titanium dihydride? I know that has been sold as a titanium 'substitute' that burns white like titanium. Just a thought. Edited September 12, 2021 by FlaMtnBkr 1

I know that has been sold as a titanium 'substitute' that burns white like titanium. Just a thought.I take XRF analysis and 82% of my composition loss in ignitionso talk to the operator and he recalculate that,the result is .... Compound Concentration (%W/W) TiO2 85.67 Al2O3 6.66 Fe2O3 2.10 SiO2 1.48 MgO 1.00 V2O5 0.93 Na2O 0.615 Cl 0.094 CaO 0.084 SO3 0.033 K2O 0.018 Cr2O3 0.011 LOI* 0.00 Total 99.96 * Loss on Ignition (600 oC, 2 h)
FlaMtnBkr Posted September 17, 2021 Posted September 17, 2021 So I would guess that is some type of titanium ore that hasn't been processed to turn it into titanium metal? Probably not very useful unless you want to try to make paint.

Either he didn't read the description closely enough or he got ripped off if it was advertised as Ti metal. Edited September 18, 2021 by SharkWhisperer

FlaMtnBkr Posted September 19, 2021 Posted September 19, 2021 Most titanium is an alloy and not pure titanium. But not knowing if it was Ti before or TiO2 and just that it was TiO2 after doesn't tell much. Titanium ore as mined from the ground would look very similar to those results, and is converted to Ti metal by the knoll process I believe. Edit: No, the Kroll process: https://en.m.wikipedia.org/wiki/Kroll_process Regardless, it doesn't work for your purpose and I suspect that 85% titanium with the remainder mainly aluminum, some iron, silicon, magnesium, and vanadium, etc, would burn just fine. While oxidized metals would not. Though the first is just a guess... 1

Titanium is almost always an alloy of 90% titanium, 6% aluminum and 4% vanadium, at least what I've seen advertised by pyro suppliers. 1
