Effect of initial substrate conditions on growth of cubic silicon carbide

In order to analyze the epitaxial growth of cubic silicon carbide by sublimation epitaxy on different substrates, four different 6H-SiC substrates preparations were used: (i) as-received, (ii) re- polished, (iii) annealed and covered by silicon layer, (iv) with (111) 3C-SiC buffer layer.

Silicon Carbide - an overview | ScienceDirect Topics

2875. Silicon-carbide is commercially produced from silica sand (quartz) powder and petroleum coke (CPC)/anthracite coal in required proportion in an electric furnace. Heat at the core of such furnace reaches as high as 2600 °C. A yield of 11.3 ton black silicon carbide is obtained from a furnace charge of 75 ton by this process.

Silicon Carbide - an overview | ScienceDirect Topics

If silicon carbide cannot be polished efficiently at a high precision level, it becomes difficult to use this material in any optical or electrical device. As a nonmechanical or noncontact method of machining, CO 2 lasers can be used to directly machine silicon carbide without needing to worry about tool wear or low removal efficiency [5] .
