· S4 Pr2

S4 Pr2 is a rare-earth compound in the praseodymium family, likely a functional ceramic or intermetallic material developed for specialized electronic or magnetic applications. This appears to be a research or specialized-use material where the exact composition and production method are proprietary or still under development; it is not a widely commoditized engineering material.
