Graphite is the stable form of carbon. 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.<\/p>\n

Carbon\/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.<\/p>\n

Our carbon\/graphite rods are CVP™ (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.<\/p>\n","protected":false},"excerpt":{"rendered":"
