Graphite
Electron Microscopy Sciences Graphene on Silicon Nitride with 2.5 µm holes, 3-5 layers, 1.0-1.7 nm thick, 85.8-90.4% Transparency
High quality graphene chemical vapor deposition graphene is layered on a silicon nitride TEM substrate. The substrate is 200 um thick 3.0mm hexagonal silicon with a 0.5 x 0.5 mm aperture and 200 nm thick silicon nitride membrane with approximately 6,400 2.5 um holes. Graphene coverage of the TEM grid is better than 75 percent.
The substrate is a solid hexagonal disk with a greenish hue. The graphene film appears as a near-transparent to light-grey film on the surface of the microporous Silicon Nitride membrane.
Layers: 3-5 layers
Thickness: 1.0-1.7 nm
Transparency: 85.8-90.4%
Acs Material EXP GRAPHITE, ATART 300, 200G
Expandable Graphite, Start 300, Expand 170, | 7782-42-5 | 200g | Expandable graphite from ACS Material is a specially synthesized intercalation compound of graphite. Graphite’s flaky, layered structure makes it possible to introduce outside atoms or small molecules between the graphite layers. This process is called intercalation and the result is an expandable graphite salt or a graphite intercalation compound (GIC.) The material gets its name because, when exposed to heat, the intercalated graphite layers expand and separate like an accordion. The final expanded volume can be hundreds of times greater than the initial volume of the material. The intercalation agent and the proportion of intercalated layers determine the temperature at which expansion begins and the rate at which expansion occurs.

Electron Microscopy Sciences Synthesized Graphene Powder
Graphene is the ideal support film for electron microscopy. It provides an invisible, crystalline background that enables the unrivaled TEM characterization of organic and inorganic nanomaterials. Graphene is atomically thin, chemically inert, consists of light atoms, and possesses a highly ordered structure. Graphene is electrically and thermally conductive, and is the strongest material ever measured.
We offer ultrahigh-quality graphene that is produced through the substrate-free gas-phase method which results in a highly ordered structure that is composed of 99% carbon by mass (1% hydrogen).
