Material mentioned in video is zirconium dioxide, I don't think that is ceramic, it's more like a metal.
I am not sure. At around 2:00 in the video, the guy mentions that Zirconium Dioxide is a ceramic material.
If you google "zirconium dioxide ceramic", the first result is a Wikipedia source that states: "
Zirconium dioxide is one of the most studied ceramic materials." At the same time, if you ask google, "is zirconium dioxide a metal", it tells you "
Zirconium dioxide, also known as zirconia and zirconium oxide, is a crystalline metal oxide that has found its way into the ceramics industry."
