Pictures of Iris Alexander LK99 Samples

Iris Alexander had the first publicly claimed LK99 levitation and now has claimed to have low resistance at about 7 degrees celsius.

She is giving her ingredients and pictures of her samples.

The ingredients (MOLAR %)
– 23,5% PbSO4;
– 70,5% PbO;
– 3,5% Cu3P;
– 2,5% PbSiO3.
Cooled reasonably fast, crystalline structure should be kinda like this

Not the last hope. There is also the original korean thin film and any others who continue to try to measure samples.

  1. The reported current density is very low; even if this is real it will only be suitable for small power applications.

    A high current density superconductor running at commercial refrigerant temperatures would be a lot more exciting than a room temperature one with low current density, IMHO. Heck, who doesn’t own a freezer nowadays?

  2. Once again not a superconductor, no zero resistance, no susceptibility or heat capacity measurement, please give it a rest. There’s nothing here.

  3. Needa help from Walter White. The public needs the exact steps and mix to replicate. If there is that much white shell and crust around the material how do you really know what amount of chemical was absorbed in the material as doping the impurity.

  4. Iris sounds like some delinquent street punk who thinks it’s a genius… This is exactly why the over civilizied woke free nations give positions to anyone and not filtered correctly like in the past.

      • Not known for wokeness, no. But well known for corruption, officers prostituting their soldiers to homosexuals to make some money under the table, dedovshchina that frequently involves sexual favors (it’s only gay if you are on the recieving end and unwilling; apparently) and HIV-rates that look like Africa.

      • She’s also an apparently sincere supporter of the semi-fascist authoritarian communism of the USSR. I guess certain idiots might think that’s woke, but that should be a head scratcher if you’re expecting wokeness.

    • Her personal beliefs and attitude should have nothing to do with rather she’s competent or not. Attack her work not her person.
