Silicon is the 2nd most abundant element in the crust and 8th most abundant in the Universe. Silicon Carbide was first discovered in 1891 by E. G. Echeson. Silicon Carbide is formed very rarely on Earth.

Silicon carbide explained

Silicon carbide is an important material in TRISO-coated fuel particles, the type of nuclear fuel found in high temperature gas cooled reactors such as the Pebble Bed Reactor. A layer of silicon carbide gives coated fuel particles structural support and is the main diffusion barrier to the release of fission products.

Ferrock: A Stronger, Greener Alternative to Concrete

There are literally mountains of flyash laying around in Europe without anybody wanting to use them for concrete. My first thought was maybe silicon carbide, since it can be made with readily available silicon and carbon. If you don’t do this then all the air in the room is also heated up to ludicrous temperatures, and that tends to
