Zk. Huang et al., FORMATION OF N-PHASE AND PHASE-RELATIONSHIPS IN MGO-SI2N2O-AL2O3 SYSTEM, Journal of the American Ceramic Society, 77(12), 1994, pp. 3251-3254
Formation of N-phase in the system Mg,Si,Al/N,O was studied. Its compo
sition was confirmed to be MgAl2Si4O6N4 (2Si(2)N(2)O.MgAl2O4). Subsoli
dus phase relationships in the MgO-Si2N2O-Al2O3 system were determined
. The results are discussed by comparing with two similar systems, CaO
- and Y2O3-Si2N2O-Al2O3.
