The decomposition of methane has been studied experimentally in contact with various oxides at elevated temperatures. For each oxide, the temperature at which the cracking starts has been determined. No correlation was found to exist between the temperature for the onset of cracking for a given oxid...

The interactions between carbon and nitrogen in liquid silicon have been studied experimentally. High purity silicon was melted in silicon nitride crucibles under an Ar atmosphere with a graphite slab inserted in the crucible prior to melting as a carbon source. The system was thus simultaneously eq...

Using the thermodynamic software FACT, and the SINTEF database for high purity silicon, the interaction coefficients between the doping elements boron and phosphorus and a range of impurity elements (Al, C, Ca, Cr, Cu, Fe, Mg, Mn, Mo, N, Na, Ni, O, Sn, Ti, V, Zn, Zr) have been calculated in liquid s...
