[...]The material has been nicknamed “reddmatter”, after its colour and as a nod to a material from Star Trek. It found that name during the process of creating it, when scientists found that it surprisingly switched to become a “very bright red” while it was being created.
Professor Dias and the team made the material by taking a rare earth metal named lutetium and mixed it with hydrogen and a small part of nitrogen. They were then left to react for two or three days, at high temperatures.
The compound came out a as a rich blue, according to the paper. But it was then pressed at very high pressure, when it turned from blue to pink as it reached superconductivity, and then again became a rich red at its non-superconducting metallic state.[...]
It is one of the rarest and most expensive of the rare earth metals with the price about US$10,000 per kilogram, or about one-fourth that of gold

Any traders on board hovering over prices already?

it needs to be a room temp super conducter to have any significance.
The total global demand for rare earth oxides (REOs) is expected to increase from 208,250 metric tons in 2019 to a forecasted 304,678 metric tons by 2025. REOs are used for a variety of applications, including in permanent magnets, in batteries, in catalysts, and more.
[...]When they dialed the pressure back up to as little as 0.3 gigapascals, the blue fleck turned pink as the electrical resistance plunged to zero. The substance reached a peak superconducting temperature of 294 K—7° warmer than the original CSH and truly room temperature—at pressures of 1 gigapascal. Magnetic measurements also showed the sample repelled an externally applied magnetic field, a hallmark of superconductors. The paper, the authors say, went through five rounds of review.[...]

Like most of the rare earth elements isn't redmatter only found in China?
I googled my question but couldn't get a straight answer. 🤔
Lutetium is obtained from the minerals bastnasite and monazite, where it occurs as an impurity and is mined in the USA, china, Russia, Australia and India.1 In southern West Virginia it is generally found in areas where the No. 5 Block, Stockton, Coalburg and Winifrede coals containing high Lu (>0.40 ppm) are mined. Lowest Lu samples are also concentrated in north central West Virginia.

The answer to both was in the article.
20.5°C for temperature and 145,000 PSI for pressure.

All the big fellas, actually.
