What happens to lead then you overheat it beyond its melting point, and what metal or chemical does it become then?

What is strong and brittle. If you cooled the melt back down, you might easily have a microstructure resembling some high temperature phase that is frozen in. This will depend on things like composition and cooling rate.jacques said:Nope, I’m not mixing anything, just want to know why lead suddenly change to some weird burnout lead, it look like lead, but it’s strong in a way and brittle.
Lol, I’m not that sure man, it’s probably old news in NASA. but if found anything usable about my “burned up can liner” please let me know?Maybe you have discovered a "buckycan" form of carbon!
I was concerned about lead vapour. The temps you're creating could liberate some elements that would normally be inert and harmless.Jacquesl said:Dave, it’s not like I’m filling my room up with SO2 gasses, It’s just a can, man

chemisttree said:If you understood the process well enough, you could, for example, put an additive in diesel fuel that produced a magnetic soot particle. That particle would find its way into the oil and be removed by a magnet.
Activated carbon is difficult to remove by filtration and filter aid must be used. magnetic filtering would not require a filter or filter aid. There are many, many uses of magnetic activated carbon. Mercury removal in coal fired power plants, for example.
chemisttree said:If you got your "lead" from wheel weights or lead acid batteries, the hard brittle stuff left over when you distill out the lead is antimony. Antimony is hard, silver to gray and brittle. It will cause contact dermatitis, conjunctivitus (pink eye), nasal ulceration. Bad JU JU! Keep it away from any of your hydrogen experiments since it will form extremely toxic, volatile hydrides.
Find the Merck Index at your local College library and make friends with it.
Just a note... I hope that when you are doing this kind of stuff you aren't inhaling or you are using a good hood. A garage with a few open doors really won't cut it.
The melting point of lead is 327.5 degrees Celsius or 621.5 degrees Fahrenheit.
When lead is heated beyond its melting point, it will transition from a solid to a liquid state. This process is known as melting.
No, lead does not undergo any chemical changes when it is melted. It remains the same chemical compound, but in a different physical state.
No, lead will always melt when it is heated beyond its melting point. This is a characteristic of all substances with a defined melting point.
Liquid lead has a higher density and is more malleable than solid lead. It also has a lower melting point and is able to flow and take the shape of its container, whereas solid lead is rigid and maintains its shape.
