Seal Technologies | KSB

The Silicon Carbide Advantage. KSB uses silicon carbide seals, which have the following benefits: The silicon carbide seals have a surface hardness of 2700 Vickers, compared with the next best material, Tungsten Carbide, which has a hardness of 1500 Vickers. The harder surfaces are more resistant to abrasion wear, resulting in longer life.

The Ins And Outs Of Silicon Carbide - Semiconductor …

2020/3/19· Palmour: Silicon has a bandgap of 1.1 electronvolts, and that is basically the definition of how much energy it takes to rip an electron out of the bond between two silicon atoms. So it takes 1.1 electronvolts to yank an electron out of that bond. Silicon carbide as a band gap of 3.2 electronvolts, and so it takes 3 times more energy.
