  2. A little less than 40 minutes left to go. Which mineral will win? Vote, vote, vote! #MinCup23 #Moissanite #Kaolinite

  3. Just letting everyone know that I voted for #Moissanite in the first round of #MinCup23 mostly because I saw a lot of support for its rival that shall not be named and I'm a contrarian by nature.

  4. Not sure what to vote for in match 1 of #MinCup23? Here's a summary:

    #Moissanite
    SiC
    Name: after Henri Moissan, who discovered it in Canyon Diablo Meteorite
    Natural occurrence: as presolar grains in meteorites; in kimberlites (origin: Earth's mantle)
    Neat fact: changes color when heated
    #Kaolinite
    Al2(Si2O5)(OH)4
    Name: derived from Gaoling, China
    Natural occurrence: widespread weathering product of Al-Si minerals
    Neat fact: used in prehistoric times for pottery

  5. The slippery slurry is ahead! Have the star stuff fans been snuffed? If you haven’t voted yet, there’s still plenty of time. #MinCup23 #Moissanite #Kaolinte

  6. We have crystals that formed in other stars! Dissolve some meteorites almost completely, and some of the residue is SiC -these grains have carbon and silicon isotopes produced in red giant stars and supernova; from before our solar system formed. See Larry Nittler's (now at Arizona State University ) presentation:

  7. I used to have a set of dinnerware, but now it's just mullite. can take the heat -up to 2500°C.

  8. Is it the synthetic form of star stuff, or the slippery, soothing slurry? Make your choice and VOTE NOW! #MinCup23 #moissanite #kaolinite

  9. The first commercial LEDs were based on synthetic #Moissanite. 3H-SiC was used for yellow LEDs in and 6H-SiC was found to emit blue light. Unfortunately, SiC has an indirect bandgap, therefore nowadays, the more favorable GaN is used, which has a direct band gap and is about 100 times brighter. #MinCup23

  10. I'll start some early campaigning for #Moissanite, because synthetic #Moissanite (SiC) is also super-interesting from a materials science perspective 🤩 #MinCup23

    Natural #Moissanite has a huge color variation from green and blue to black depending on composition. It was first identified in 1904 by Henri Moissan in a sample from the Canyon Diablo meteorite found near Barringer Crater.
