Graphite is one of the softest; diamond is one of the hardest minerals known to man. Carbon is harder than graphite. For TEM and SEM applications, graphite is recommended.\n\nCarbon\/graphite films are most usable in TEM and SEM due to its value characteristics: uniformity amorphous and high transparent to electron beams. Because of low molecular weight and their unique structure (graphite have a sheet like structure, where the atoms all lie in a plane), carbon\/graphite films have excellent mechanical stability, and even film thickness is about 1-2 nm.\n\nOur carbon\/graphite rods are CVP\u2122 (Chemical Vapor Process) purity and spectrographic grade, grade 1, produced to ASTM tolerances or even tighter as well \u2013 we have a technical grade. The technical grade has a typical impurity level of 50ppm or greater. Technical grade may be used in applications of non critical SEM coating applications.\n","protected":false},"excerpt":{"rendered":"<p>Carbon Rods (graphite) with an impurity level of 2ppm or less with a maximum level element of each of 1 ppm.
