Does anyone have experience with this in a ball vape? If so, which vape? How did it work? Did it impact your operating temperature? Which is better in your opinion?
Zirconia balls instead of rubies in ball vapes?

Zirconium Dioxide Properties, Production and Applications - Matmatch
Zirconium dioxide, also known as zirconia and zirconium oxide, is a crystalline metal oxide that has found its way into the ceramic industry. Read more about how zirconia is one the most commonly used materials in various industries and application areas.
Zirconium dioxide has a thermal conductivity of 2 W/(m·K), which makes it perfect for situations where heat needs to be contained.

so it's more like borosilicate glass (around 1W/m*K) , and boro beads are much cheaper....

Thanks for posting that link, I enjoyed it, very informative.
hello I'm looking for balls that are as safe as possible, I was thinking of boro balls this one: https://m.it.aliexpress.com/item/10...2218fcNP1jpw&mp=1&gatewayAdapt=gloPc2itaMsite"Zirconium Dioxide Properties, Production and Applications - Matmatch

But also ruby but i don't know if is safe as boro
Ruby: https://m.it.aliexpress.com/item/10...2218fc9jUV6C&mp=1&gatewayAdapt=gloPc2itaMsite
I'm interested in safety and efficiency, I know rubies conduct better than boro balls, but are they so much better if we don't count the recovery time?

I might order the glass ones, how do you know it is boro glass? I'm a bit afraid of breaking them. They are way cheaper then the rubies though.
we are in the same boat, however I ordered them and they must arrive at the end of March, I asked the seller and he said they are boro balls, you can only trust them and check when they arrive. I will keep you up to date!
I looked at the thermal properties and didn't think they would be a good material for ballz. Perhaps as an addition to other balls, they could increase heat retention marginally. Smaller balls are less likely to crack and I think 3mm is safe with any of the suitable materials. It doesn't even matter if they crack!
yes I know, but before taking the ruby I want to try the boro ball

Stainless steel has around 16w/mk, is a lower number better for keeping the heat?
it seems to me that it is around 40, however one thing is the data on paper another is the real tests

around 40 W/m*K as mentioned..
then Rubies tend to hold heat better than Stainless steel, yep

Wouldn't a high conductivity number (rapid heat exchange?) mean that they lose their heat faster?
Edit, if I understand it correctly a high conductivity number means a lot of heat can be removed when in contact with air.
Would that mean to get the same hot air effect you would need more boro balls because they don't give off the heat as well as the rubies, but they will cool down slower because they retain the heat longer?

ye I understand.... it's actually a bit hard to find an official post about x beads vs y beads because in the industry they don't use beads usually, because of the risks of beads falling on somebody etc', safety is important when you work with big systems with high temps etc'....
no, for example wood has a very low K value and it's a great insulator (because of its air pockets)

Rubies is the best solution for people who want to mimic the Glass Symphony XLR into a smaller build. because GS used boro beads, and Rubies K value is much bigger than Boro, hence it keeps the heat better, but with overall smaller build. so you "mimic" a huge GS into a smaller build. available for very fast draws.

Ceramic seems to be the hot ticket for dabbing cups.
Ceramic balls for soaking up heat?

Ceramic has a K value of 3.8W/m*K so I think Rubies are better overall

I do think for dabbing cups the function is just to stirr without impacting taste too much.
To sum up the values:
Rubies: 40W/m*K
Stainless Steel: 14W/m*K
Ceramic (zirconium): 2W/m*K
Boro: 1W/m*K

Crazy K value
Depends how much the beads cost but it's very high value, dunno if beads even exist with its hardness of material?

Sounds like something smells purple.
Heat capacity makes a difference too. Higher heat capacity and heat conductivity allow for more heat storage and faster transfere of heat and recovery time.
On paper it looks like SiC is top and Corundum/Rubies next. Aluminium nitride looks better, but given that the thermal resistance changes with heat the temperatures we run our injector heads at Silicon Carbide may be better. SiC has a more stable thermal conductivity, and a higher thermal capacity. Definatley looks like its better than Ruby. Silicon nitride isnt quite upto Rubies performance. On paper.
My placebo effect tells me pool balls would work well if i could just make an injector head big enough.
Had to edit, Just looked at the price of the bowl and coughed vapour everywhere. $149 for a tiny ceramic bowl? you could get a huge arse crucible made of Sic for that. You could fit alot of concentrate and balls in a Sic crucible thats 11cm high x 9.5 wide at the top. For $15 from china. And ruby looks prettier.

it has a lower maximum temperature than SiC, I imagine it would be easier to form into any shape while hot than Sic because of that.

yeah, you're right. the cp value of SiC is much lower than the cp of the Rubies, hence it's easier to warm SiC, the beads will be ready sooner. so it's better by its K value and cp. only question left is how much SiC cost vs Rubies or Boro beads? boro has great cp value but not too good K value.

I have both for my Switch. The SiC does seem to work better.
Also have a sapphire cup I haven't used in quite a while, where does it rank?
