Making Elemental Boron from Borax (Element Series: 10)
HTML-код
- Опубликовано: 27 сен 2023
- Boron is a weird element, a lustrous crystalline metalloid. Most won't come into contact with its elemental form as it has few uses. Boron starts to shine when it bonds with other elements. It is a chemist's best friend. Borosilicate glass makes up almost all the glassware in the lab. The Boro suffix is thanks to the inclusion of boron trioxide in the glass. Adding boron decreases the glass's thermal expansion, making it more shock-resistant than ordinary soda lime glass. The shock-resistant property makes it useful for equipment under constant thermal gradients. Now, with that tangent out of the way, boron time.

Awesome video as always, and I too am a fan of the bag mill hahah
Hey I'm fallin love with your content 💕💕 great job man! 🤠
Love from India ❤️
I always learn so much from your videos. You do such a great job making them. This one was no exception!
Glad you enjoyed, Thank you! I always appreciate your kind words.
That looks like a fun experiment for the 4th of July which would be soon. Imagine that being a good science lesson for that day.
Tis!
Interesting :D The more you know^^
Science!
Interesting videos. Please be safe!
I wonder if you could use aluminium and iron oxide to produce ferroboron it should also collect more of the boron and dissolve it in hcl to get boron
Using coarser magnesium slows the reaction down but you end up with much lower yield since there's a lot of unreacted reagents and sometimes it doesn't even want to lit. I think it's better to add some kind of flux, it's a common tweak when making thermites that burn too fast. I don't know what kind of flux would work, maybe dry magnesium chloride? I'm afraid common fluxes might react with boron. Also sulfur speeds up thermite reactions, are you sure you need it in the mix?
Yeah, I discussed the switch of magnesium size in the video to slow down the reaction, sulfur was used to increase temp not speed up reaction, an oxidizer like potassium nitrate would be used to speed up the reaction. Over all its a pretty bad reaction for making pure boron, lots of hard to remove compounds.
@@WheelerScientific Yeah, I know. But since methods to produce purer boron include working with diborane or boron trihalides I don't think this method is bad tbh
Hello I was wondering if hydrolysis of magnesium boride produces diborane can you help?
Cool
Science!
Me when you don't calculate percent yield for us 😩😫
I forgot to weigh out the split mix so I couldn't do a proper calculation, needless to say it was low...
A minor typo in the title - it should be from not form.
Whoops, thanks for pointing that out!
But does it burn green in the dark?😅
Maybe you should cover termite with brick next time
Yeah, I was worried about pressure building up, I think just by slowing the reaction down with larger chips, in a bigger crucible can take care of most of the problems.
@@WheelerScientific just leave a small hole like nurdrage did, it won't be oxidizing as much
