Carbide-derived carbon - Wikipedia
The production of SiCl 4 by high temperature reaction of Chlorine gas with Silicon Carbide was first patented in 1918 by Otis Hutchins, with the process further optimized for higher yields in 1956. The solid porous carbon product was initially regarded as a waste byproduct until its properties and potential appliions were investigated in more detail in 1959 by Walter Mohun.
