Practical Fundamentals of Chemical Engineering - EIT

There was no element in the group that fits the properties of the element below silicon and to the left of arsenic. Mendeleev left that position empty and proposed that the element that belonged there, which he called eka-silicon, was simply yet to be discovered. 2C 2 H 6(g) + 7O 2(g) —-> 6H 2 0 (g) + 4CO 2(g) C 3 H 8(g) + 5O 2(g

Silicon Carbide SiC - STMicroelectronics

Silicon Carbide (SiC) is a wide bandgap material. Wide bandgap technologies have many advantages compared to Silicon. Operating temperatures are higher, heat dissipation is improved and switching and conduction losses are lower. However, wide bandgap materials are more difficult to mass produce compared to silicon based ones.
