US5295305A - Razor blade technology - Google Patents
A razor blade includes a substrate with a wedge-shaped edge, an interlayer of material selected from the group consisting of silicon, silicon carbide, vanadium, tantalum, nickel, niobium, and niobium-molybdenum alloy and alloys of such materials on the tip and
Silicon carbide is harder than aluminum oxide, but more friable. Super-abrasive diamond pastes are useful in ferrous polishing or lapping appliions where heat and reactivity are not a factor. Cubic boron nitride (CBN) is a superabrasive grain with hardness second to diamond and a cubic crystal structure.

Refractories and Classifiion of Refractories – IspatGuru
Some appliions require special refractory materials. Zirconia is used when the material is required to withstand extremely high temperatures. Silicon carbide and carbon are two other refractory materials used in some very severe temperature conditions, but they cannot be used in contact with oxygen, since they oxidize and burn in atmospheres containing oxygen.

The electronic properties of bilayer graphene - IOPscience
19/4/2013· All of the levels are fourfold degenerate, due to spin and valley degrees of freedom. The corresponding Hall conductivity is shown schematically in figure 5( a ) . There are steps of height 4 e 2 / h between each plateau, as expected by consideration of the conventional case, but the plateaus occur at half-integer values of 4 e 2 / h instead of integer ones, as observed experimentally [ 2 , 3 ].
A Guide to Selecting the Right Rod
Silicon carbide, or SiC, is usually considered the best material today. It offers a super smooth surface for less friction on the line during the cast and the retrieve. Less friction means longer casts and less heat, and heat kills when it comes to fishing lines.
