Chemical extraction of silicon from sand

[gordon.sarratt]

I love that the video ends with, “and that’s how to extract the element silicon from sand” as if I’m smart enough to do any chemistry more complex than baking a cake.

Next: let's make a graphics card out of it

Why extract silicon from sand when there’s a whole valley in California made out of it

[dustinedwards]

Cool! I’ve had extracting elemental silicon from sand on my bucket list for ages, then doping it to try to make a (not very good but functional) transistor or diode.

Next video: How to extract extracted silicone from a test tube

My understanding of chemistry is that the magnesium is robbing the oxygen from the silicon oxide atmosphere like a type of thermite, I'm surprised it didn't break the glass tube. Very interesting stuff

[DarkCookes]

This can also be done with aluminum powder, but it makes lots of heat.

I really like single replacenebt reactions theirs just something about extracting an element from a compound by adding another element to the compound to replace the ion

I believe the flame coming out of the test tube might be silane, if there was water present in the sand

[Banzybanz]

I was worried the test tube was going to explode. It did get red hot.

In the first shot you used sand, in the second you used pure silicon dioxide because normal sand found in the beach contains many impurities including iron, zinc and other metals, you should clarify this.
How I noticed this: the sand at the start is clearly more yellow than the shot after (when magnesium was added.)

Now make a video that how to extract element silicon from testtube

Historical tip: sillakin used to be spelled and pronounced sil-i-con

Yes, bur the problem is that you cannot use that on solar panels! You need pure silicon! Pure silicon doesn't come from sand because it has too many impurities! Pure silicon comes from fusing high quality coal with high quality quartz at 1, 800 degrees quality coal! Glad I could help! :)

me a continuous loop of that fire pop"*

[nickgarcia]

So that’s how “sand” makes computer chips in a horrifyingly oversimplified way?

Hope u would make such beautiful nd conceptipnal videos in future also

[denisehanne]

the glas always explodes in my chemistry class 😂

Ahh * Yes the Power of Alchemy Always gets me Excited 👄🦇

Goldschmidt reduction is my favorite exothermic reaction.
