The composite helps solve some of the fundamental problems of electric mobility.
Nuremberg, Düsseldorf Robert Eckstein was the first SiCrystal employee in 1997. Even then, silicon carbide – chemical formula SiC – was considered a promising material for semiconductors. The combination of silicon and carbon is energy efficient, emits hardly any heat and takes up little space. However: the price was too high, the benefit too little. For a long time silicon carbide led a shadowy existence.
In the meantime, however, everything looks as if SiC is finally arriving where Eckstein always wanted to: in the mass market. Silicon carbide becomes a best seller. “Production for 2022 is already almost sold out,” says the managing director of the Nuremberg company.
The reason: Tesla. Since the electric car manufacturer started using the material, the demand has grown rapidly. According to the French industry specialist Yole Développement, silicon carbide sales in the overall market will amount to around one billion dollars this year. This amount is expected to quadruple by 2026.
