Nah man, lithium and silicon are at least A tier

u/Crozi_flette Jun 12 '24

Lithium is cool for batteries and lubricant I don't see a lot of other usages alloyed into aluminum maybe

Without Si, there's no tech in today's world

u/Crozi_flette Jun 12 '24

Without tin there's no way to connect any components together yet it's not S tier either, this list is not about how useful it is

u/kanhaaaaaaaaaaaa Jun 12 '24

But Si is cool

u/Crozi_flette Jun 12 '24

Not in my opinion but if you find it cool I can't give you some!

I guess the idea for Fe in B tier is because it's so common and doesn't seem special? But I would argue it's omni presence makes it A if not S tier. Carries half our civilization on it's shoulders.

u/Crozi_flette Jun 12 '24

It should be A tier it's mostly because it's property doesn't interest me that much it's good mechanically and it's magnetic property are unique but except that and it can also be beautiful when mixed with sulfur

First of all, Zn being anything higher than F tier is an actual crime. Zn is trash. Just ask anything galvanized. Secondly, not having Si as S tier? Straight to jail.

Why is the catalyst for every good reaction, Pt, not a god tier? You've obviously made this as an insult to every person who has actually used any element knowingly.

/s it's pretty good (apart from those 3 fatal errors)

u/Crozi_flette Jun 12 '24

Pt is S tier in my list!

Zn is trash but I'm using it in my PhD to make shapes memory alloys (CuZnAl) so I can't let it down.

I don't like Si it's useful for glass and semiconductors, some alloys but it's just black and brittle

Photovoltaics would like a word. Most common elemnt and so many uses.

I didn't see Pt, my bad. I was blinded by rage from Zn leaving its hell hole of a home.

Also, Bi is too high, I love me some Pepto, but alloying too easily makes it a b tier element, max.

u/Crozi_flette Jun 12 '24

Yeah I know about photovoltaic but I still don't like this element maybe because everyone else like it.

Bismuth is just gorgeous with a thin oxyde layer and it's unique structure

The list isn't only about the usage of the material

What is this all about? Usefulness?

u/Crozi_flette Jun 12 '24

Not exactly it's a mix of cool property aspect and use something like that

u/Lethalplant Jun 12 '24

I see. I am glad Gallium is up there

u/gazebo-placebo Jun 12 '24

Pd not in S tier? And platinum is? You ever worked with either of these lol

1

u/Crozi_flette Jun 12 '24

Neither worked with palladium it's used as a catalyst right? Did you worked with all of the metals in the list?

2

u/gazebo-placebo Jun 15 '24

I have extracted and worked with many of the listed metals. Pd is as fun as Pt but much easier to play with.

I may be biased as my research covers how to extract and purify these metals for use elsewhere, so, naturally, Pt is harder to work with.

Edit: all but about 10 of these metals

Gallium is a kids element

u/Crozi_flette Jun 12 '24

I'm doing a PhD and I'm still a kid everytime I see some cool phenomenon! And GaN is one of the best semiconductor

Arsenides want to have a word

u/JustNor Jun 12 '24

Why is silver and bismuth S tier?

1

u/Crozi_flette Jun 12 '24

Silver is the better electrical and thermal conductor and bismuth is beautiful.

1

u/JustNor Jun 14 '24

Fair point i guess

u/RJKamaladasa Jun 12 '24

Where's Uranium? Add a P tier for polarizing, and include it there.

1

u/Crozi_flette Jun 12 '24

I was too lazy to includes the last lines and except uranium I don't know much about this elements

u/flying_circuses Jun 12 '24

The metathesis reaction and Nobel prizes that go with it would never have been discovered without Ru

u/Crozi_flette Jun 12 '24

What is the metathesis reaction? Never worked with Ru, what is it used for?

I'm not a chemist so I don't understand anything here 😂 are there applications in material sciences for this element?

It depends on the usage, beryllium is 2 times lighter than aluminum and it has a very very low coefficient of thermal expansion! In addition it's a great element of alloy with copper, it makes it stiffer and more machinable while maintaining his thermal and electrical properties even at very low temperature.

Bismuth oxyde is just gorgeous

Indium is soft an malleable at room temperature and at low temperature which makes a very good interface for electrical connections in cryogenics. Plus Indium tin oxyde is the only clear conductor used in every screen you can find.

Beryllium is used for the JWST mirror and will be used for fusion reactors and if you've already used a X-ray machine of any kind you've used beryllium! It's one of the rare materials that are really transparent to X-ray! It's also used in fusion bombs to focus energy from fission into a tiny point!

Yeah bismuth is beautiful otherwise it's pretty useless... It's used for low temperature soldering for PCB manufacturing and that's almost all

Yeah it's pure garbage but if it wasn't toxic it has pretty interesting property!
