In this video, we show you in detail how to make a platinum contact that is suitable for the Ostwald-Oxidation of ammonia to nitric acid. Enjoy!!

nice job/ used far less matal than i imagined
Thank you very much!
This is so cool!!! I've been doing a lot of experimenting with platinum catalytic propane heaters lately, and I've always wondered if it would be possible to make one myself. After watching your video it definitly appears to be feasible! A friend of mine recently opened up a small automobile catalytic converter with an acetylene torch, and obtained the ceramic honeycomb inside. When I decide to chemically process it, instead of trying to obtain a bead of the metals it contains I may just keep them in solution and apply them to some quartz wool like you did here. Thanks for the inspiration!
Hands down, one of the best chemistry/science videos i have ever seen. Nice work. The music was spot on. W special emphasis to the pipette filtration segment as well as the dissolving of the residue in the bowl w the stirrer going . Thank you Astral 💚
Is it possible to use the same route,to produce a gold catalyst?
Really nice video. I'd just recommend you adapt the volume of music and voice a bit, when the music comes, I have to turn down the volume so much that later I can't hear the voice...
Amazing! Using ammonium chloride and sodium hydroxide solution, one can cheaply produce anhydrous ammonia gas. Using this catalyst, the production of nitrogen oxides and nitric acid becomes basically OTC!
Amazing!!!! You are the first amateur chemist I have seen attempt this!! This catalyst is so cool and I have been wanting to have some for quite a long time.
Thank you very much!
killer intro!
Hi, great video, I'm trying to replicate the Ostwald process too. Where did you get your quartz wool? I looked on ebay but I can only find glass wool. But I'm thinking glass wool might melt from the heat of the reaction. Thoughts?
Good question! I wonder if Astral Chemistry would be willing to open a web store to sell finished catalyst wool?
Thank you for your high quality videos. A joy to watch.
Thank you very much. After a year now we start to figure out how editing works.
Thank you for showing us this process and your methodology!
Pt is a pretty mysterious and amazing element.. Put a Pt/Nb sheet in a wood smoke stream and you can smell all the transformed compounds produced by it (consumes it, though..)
Where did you get quartz wool
Washington dc will be completely leveled to the ground
Where did you get the quartz wool?
Big thumbs up for showing the process, we are currently purifing crude platinum for exactly this process
(But we need a lot of time for editing...)
But please make your videos a bit shorter and to the point if you can (:
Thank you for your opinion.
Nice one. An OTC Oswald process is truly epic... Hence the music i guess
I hope the next video is on the Ostwald process itself. Would be great to see numbers on the efficiency of the conversion
The video for the process came before this one, there’s a link in the description.
@GRBTutorials I was thinking more on a series of videos optimizing the oswald process, such thats is usable for the amateur. Like the sodium series. That video you mention is more like a proof of concept...
great video, not sure how you got 1mg as an excess of NaCl though.
20mg/195ram=0.1mmol Pt
0.1mmol x 2shoichiometry x 58.5rmmNaCl = 11.7mg NaCl
edit: you allso say "0.42 mg of sodium chloridde"
Awesome video!!!
Thanks!!
Interesting video but for the love of all that you care about, adjust the volume of that crappy music you use without any kind of logic at 11:20 or so and in some other videos of yours. You go through long stretches of relatively quiet or even silent footage then suddenly, insanely louder techno music destroy your eardrums, especially if you use headphones (I do)...
platinum seem waste a lot in solution?
A very small amount of platinum is enough to turn the solution deep black. However, the platinum is easily recycled.
wow
Hi have you considered using a tilly lamp mantle thats 99% thorium dioxide as a catalyst? that was the other catalyst used industrially when pt ran short in ww1. my research gives 11 parts ammonia gas 89 air run through preheat 700c and use gasflow to push the exothermic catalyst temperature to 800-850c. Above 900, selectivity is reduced. thorium ran at atmospheric pressures, pt 4-5atm. 2 cooling chambers are used, 1 has water vapour added, one has o2. but we can use h2o2 bubbler instead.
Apart from its fragility i think the tilly lamp mantles may be ideal, for surface area and contact times, easy to apply and clamp to a tube etc
Surely a stupid question but at 8.07 and at 8.16 I cannot tell if you are adding water or blowing air into the solution. Is it water or just air or both ?
Not a stupid question. We noticed that it is very hard to tell on the video. Its just synthetic air we blow over the solution in order to facilitate the evaporation process.
Bumblebee Hive . Air to dry it.

First! :P We discovered that we have been running a lab for years without having sodium chloride. But a good chemist always has some sodium and chlorine gas, am I right?
