High Quality Silicon Carbide Graphite Crucible

Clay graphite crucibles are OK, but they are very susceptible to thermal shock, which means if they are heated too quickly they will crack, silicon carbide crucibles do not suffer from thermal shock. A five to seven year service life from a high quality silicon carbide crucible is not unusual at hobby foundry level, as long as the crucible is properly cared for.

Predicting Two-Dimensional Silicon Carbide Monolayers …

Mixing carbon and silicon atoms to form two-dimensional (2D) silicon carbide (SixC1–x) sheets is promising to overcome this issue. Using first-principles calculations coined with the cluster expansion method, we perform a comprehensive study on the thermodynamic stability and electronic properties of 2D SixC1–x monolayers with 0 ≤ x ≤ 1.

Theoretical Study of Carbon Clusters in Silicon Carbide …

Using first-principles methods we performed a theoretical study of carbon clusters in silicon carbide (SiC) nanowires. We examined small clusters with carbon interstitials and antisites in hydrogen-passivated SiC nanowires growth along the [100] and [111] directions. The formation energies of these clusters were calculated as a function of the carbon concentration. We verified that the
