Abstract
En fremgangsmåte for fremstilling av siliciumnltrId omfatter at en primærblanding av sillciumdloksyd og karbon omhylles l en matrise eller et porøst sjikt på basis av karbon før karbonitrerlngsreaksjonen. Dette tillater å oppnå 813^4 l form av partikler med regulær og kontrollert form, frie for whiskers.
