Thread: Does Anyone Know the Method of Producing TiO2?

Does anyone know the method of producing TiO2?
Nowadays, I have been very interested in Titanium Dioxide, namely Tio2. But I am confused how to make it in laboratory.

Well, I can search the web like anyone I guess. The most succinct summary I found was this one: http://v.pl.3.eu-norm.org/index.pdf

Seems you can choose between chloride and sulphate processes. These are to purify it from commercially available sources.

But if you are doing this in a lab, what do you intend to start from?

burn some CP titanium

Pigment grade Titanium dioxide is produced in Western Australia from a raw material resource of mineral sands that occur on the large coastal sand plain in the South West. The sands contain ilmenite (FeTiO3) which is separated out by physical means. The ilmenite is then roasted in large rotary kilns under reducing conditions, using coal as the reductant. A by-product of this process is char that is sold as activated carbon from sites where it is not too radioactive for such purposes. The kiln treatment reduces the iron oxide component to metallic iron. This is then oxidised using ammonium chloride as catalyst in an aqueous slurry using air as the oxidant (well I have seen that process at pilot scale). The iron oxide is removed by high intensity magnetic separators and the raw titanium dioxide is then treated by the chloride process mentioned in the link above.

wow, sounds like a real simple lab process.

Indeed.

Hard to imagine why you would want to 'make' it anyway since it can be purchased easily enough.

One could dream up all sorts of schemes depending on the starting material, but the oxide is the most common material anyway so why would you bother?

One thing I wouldn't want to play around with is TiCl4, known around here as 'tickle', which is an understatement of its effects on the human body.

i think it's white powder. i think i seen it.

Thanks, Mod. Same goes for almost all this poster's "contributions", as far as I can see.

well if end you up with red powder in your lab, you might want to check with me.

there ya go >> white powder >> Titanium dioxide - Wikipedia, the free encyclopedia

i've seen the entire manufacturing process. i made a report on this process.


you want me to beat you with a stick or would you like my leg?

idiots.

There's only one idiot posting in this thread (clue: it's you).

Stop trolling please.

Moderator Comment: ASG141 - stating that you "think it is a white powder and that you think you have seen it" contributes nothing of value. If you have, indeed, reported on the manufacturing process then some of the details you gleaned in preparing that report could be relevant and useful here. Throw away comments do not any value. This should be obvious to you and should not need pointing out. Now that it has been pointed out please ensure that future contributions have some substance to them.

ASG141 and PhDemon. One form of idiocy is calling other idiots and not recognising that this will lead to suspension. Cut it out.

i could ask my colleague for the report but i think you won't get it. what else do you call an idiot but an idiot.

Since you claim you helped prepare the report and are presumably knowledgeable about its contents, you should be able to summarise those contents for this thread. If you are unable to do so there was really no point in remarking on it in the first place.

Here is another riddle for you: What do you call someone who seems determined to insult members, ignore forum etiquette and make low value posts?

Answer: Suspended for three days. Please have an improved attitude on your return.

What a relief, thanks.

Hi guys, how do you bond an oxygen atom to a carbon monoxide atom already consisting of a carbon and oxygen atom, an urgent response will be appreciated!

Homework?

hi john, yes it is

While we don't do people's homework for them on this forum if we can help it, we can give clues to aid understanding. I can give you the following clue.

In the old days, in cities the gas we used to burn was called "town gas" or "coal gas". It was made from coke and steam (i.e. C + H2O), by heating . This gas had 2 main components in it and was more dangerous than the natural gas we use today, as one of these components easily poisons someone who breathes it. In fact it was a common suicide choice to stick your head in the oven and turn on the gas. The symptoms of poisoning were identical to those of someone who is poisoned by car exhaust. What do you think this poisonous component of town gas might have been? And what do you think it turned into after it was burnt?
