  • GLASSY CARBON PRODUCT INFORMATION SPI Supplies

    Because graphite normally has considerable porosity, the ~ density is higher than the typical graphite (excluding HOPG and pyrolytic graphite). As a consequence of this high density and the lack of porosity that plagues ordinary graphite, the SPI Supplies glassy carbon can be polished to a mirror finish. It looks like a "black glass".
