| Abstract: | process with in which Mg3N2 was is synthesised by heating metalmiagnesium under a nitrogen stream at high temperature was introduced. Theprocess and products were analysised by TDA.TG.XRD and SEM.The CBNwas synthesized by using the Mg3N2 catalyst.It has been proved that the Mg3N2can be a suitable catalyst for CBN synthesis.The effects of process parameter.catalyst stored method and transmit pressure medium on CBN formation were discussed. |
