Abstract
L'invention se rapporte au carbure de silicium. Elle concerne un procédé de préparation de carbure de silicium caractérisé en ce que A on met à la forme désirée un polysilane répondant à la formule moyenne Ø(CH3 )2 Siõ ØCH3 Siõ et contenant 0 à 60 moles % d'unités (CH3 ) 2 Si = et 40 à 100 moles % d'unités CH3 Si cong , les valences restantes sur le silicium étant satisfaites par un autre atome de silicium, par un atome de chlore ou par un atome de brome, de façon que le polysilane, de chlore hydrolysable ou 21 à 63 % en poids, par rapport au poids du polysilane de brome hydrolysable, le polysilane ayant une viscosité de 0,005 à 500 Pa.s à l'état fondu à 150 degrés C et une viscosité intrinsèque de 0,0001 à 0,1 dans le toluène, et B on chauffe la forme en atmosphère inerte ou sous vide, à une température élevée, comprise dans la game de 1150 à 1600 degrés C, jusqu'à ce que le polysilane soit converti en carbure de silicium. Utilisation par l'industrie chimique.
