Abstract (en)

[origin: US2003165417A1] A process for the production of silicon nitride (Si3N4) is described. According to this process nitrogen and/or nitrogen compounds are reacted with silicon and/or silicon compounds in a reaction chamber by means of a subgroup element or a subgroup element oxide. The process can be carried out in a simple and rapid manner and has a high yield.
