Silicium — Wikipédia
Le silicium est l''élément chimique de numéro atomique 14, de syole Si. Ce métalloïde tétravalent appartient au groupe 14 du tableau périodique.C''est l''élément le plus abondant dans la croûte terrestre après l''oxygène, soit 25,7 % de sa masse , mais il n''est comparativement présent qu''en relativement faible quantité dans la matière constituant le vivant.

Silicon Carbide SiC Material Properties - Accuratus
Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800 C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C. The high thermal conductivity coupled with low thermal expansion and high strength give this material exceptional thermal shock resistant qualities.
