Fake Titanium

[Arw]

I try to make smokeless/odorless/indoor fountain
I think and search and read and test and did this thousand time with different material and not worked
so I suspect to my titanium
Then bought a Chinese fountain and separate titanium and use this to my fountain
and its worked!!
I bought two different titanium from two different seller
I know that titanium dosen't react with acids but what I bought react and makes deep purple solution
interesting part is this fake titanium burn like titanium in flame and make little crackle
What can it be?

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.

HCl and H2SO4

I react them by plenty of acid to separate Ti from other particle if they are

but all of them is react

I think that's an alloy and i'll find out by spend of 10$ for XRF analysis

Then i tell you

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.

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 right

I add some nitric acid and its become colorless

but two point

that was worm H2SO4(around30%) not HCl

and its react fast and make hydrogen gas by a lot of bubble but chinese one not make bubble and react toooooo slow

and the most important part is why my Ti dose not worked and chinese did?

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

I take XRF analysis and 82% of my composition loss in ignition

so 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)

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.

TiO₂ is titanium dioxide. Sunscreen and white paint pigment.

 

Either he didn't read the description closely enough or he got ripped off if it was advertised as Ti metal.

Are you analyzing the chem after you've burned it?

 

I can't see how titanium oxide would produce sparks in a comp, like you said in your original post.

You all right

I forget that to say XRF analysis report as metal oxide

I dont know why but they do!

i guess it was because they burn the sample to loss the gas element"oxygen nitrogen and ..."

so some metal will turn to metal oxide so they report all metals as metal oxide

and its not matter at all

what matter is that was an alloy of titanium and not pure titanium

[FlaMtnBkr]

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...

If it burned when you used it in the comp, it's titanium.

 

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