Formation of a new phase upon heating of the products of interaction of SiC with SiO2

Potential Semiconducting and Superconducting Metastable Si3C Structures under Pressure

“…One is close to organic chemistry here, where the size of barriers to rearrangement and decomposition is large, and so substances that are metastable may be nevertheless persistent. In addition to SiC, several alloys or solid solutions, such as Si 0.75 C 0.25 , Si 80 C 20 , , and Si 5.04 C 2.96 , , have been synthesized. The similar Si 0.75 Ge 0.25 , , Si 80 Ge 20 , , Si 0.5 Ge 0.5 alloys or solid solutions are also known.…”
