Made my first silicon in high school in 1967 by reducing molten quartz with aluminum. Poly crystalline , not amorphous. I then used it to make a copper silicon alloy which was quite pretty and good to machine. Pity I didn’t make the copper or aluminum from rocks, but it was fun and instructive. The silicon looked just like the polycrystalline chips you show. Thanks for this great video!

72 now. I doubt very much if my silicon was very pure. There was a point where you could tell the aluminum was used up, and by that time, the pool of molten quartz was hot enough to boil off any remaining aluminum. The arc carbons I used to melt with, had copper exterior, and I expect the carbon itself may have been doped with something. Besides that the quartz was unlikely to be pure silica. I didn’t feel bad though, since the really pure stuff is made by zone refining. It was fine for alloying though.

Glad to see you. Your accent remains very cool, I think those who complain about your accent or have a negative idea, can please refrain from mentioning it at all. Other than positivity, I don’t see anything that deserves to be commented bad on. This man has enough knowledge to make you get lost in your false delusional hallucinations, whether it imposes any criticism and/or unnecessary comments. Basically try to learn from him if possible:) The genius puts very much effort to do what he’s doing, if you do not appreciate the positive knowledge that he provides us with, then get a translator or enable subtitles, whatever. Find a solution, because there’s only 1 of his kind and you know it, otherwise you wouldn’t even proceed with the thought of sharing meaninglessness.

too bad for the video encoding errors but very informative on some part of the subject usually left out! (like how hard it is to refine!)

Loved the video

Silicon polymers are also used for very flexible and heat resistant wire insulation, and other heavy duty tubing. It is also used as a flexible heat conductor in some low power applications, often called thermal pads. One of the most important applications of silicon itself is in alloys, it is very commonly used in Aluminium and cast iron alloys, to change its properties, and is especially useful in aluminium castings, to make grain structure more fine. But even in other aluminium alloys it is used to improve machinability and strength. The Silicon Aluminium alloys are extremely popular in automotive and aerospace industry. Some can contain very big amounts of Silicon.

I watched some of your videos on radioactive materials because they are my favourite, but have learned way more from what I thought would be a boring video on silicon! Subbed!

I didn't know that Silicon and Silicone were related. Thanks for that.

I have had the same thought, I was coming from the fact God made us from the "dust" of the earth. Dust or finest particles /individual atoms. As I imagine our creator gave himself all the necessary elements and being the obvious master chemist, mechanical and electrical engineer, and creator of life from those elements that he was, it would be good to know every element we are made from.

I remember my dad telling me about massive quartz crystals that were lead mine tailings in Joplin, Missouri. Being the 70's, him and his friends of course smashed them to smithereens. He said they were the size of Volkswagen Beetles... I wish I could have seen them. Minus the lead contamination of course...

So Si (silicon) was used to redefinition the SI(the International system of units). 14:37 the seven SI base unit is kilogram(kg), metre(m), second(s), ampere(A), kelvin(K), mole(mol), and candela(cd)

0:57 can it also be known as PiezoElectricity?

My uncle is a professor at Cornell, he says we will outgrow silicone in the near future. Silicone can only handle so much processing speed

Wow!

They tricked a rock into thinking.

Is your glass vial with the silica/magnesium reaction pyrex? It looks like it was melting and silica wouldn't do that. 5:10 aluminium is not a transition metal
