“…006 Z, and c = 14.61X(7) (7)) The structure of 11-MoG is closely related to the cubic Bl-type ( ) . The phase is stable only at high temperatures ( 7 ) decomposing into Mo C and graphite at 1450 + 1000 (13 (Table 3).…”

Thermal properties of a reaction hot pressed Mo≤5Si3C≤1 ceramic

“…The phase identification was confirmed using EDS analysis. The overall composition corresponds to a three-phase region in the 1600 C Nowotny phase diagram [4] consistent with loss of silicon and carbon uptake is relative to the original stoichiometry. A similar compositional shift, away from silicon and towards carbon, has been reported at temperatures as low as 1500 C [9].…”

“…Classified as a Nowotny phase, it crystallizes in the D8 8 structure (P6 3/m cm) and exhibits a ductile to brittle transition around w1300 C and melting temperature approaching 2100 C [1][2][3]. It is stable with SiC and all silicides and carbides of molybdenum at 1600 C with the exception of Mo 3 Si [4]. The compound has also been investigated as an infiltrant for SiC-based composites that would allow for high temperature use [3,5,6].…”
