Glassy carbon

Glass-like carbon, often called glassy carbon or vitreous carbon, is a <a href="/facts/Graphitizing_and_non-graphitizing_carbons/oJFrk8TL">non-graphitizing</a>, or nongraphitizable, <a href="/facts/Carbon/ukrgQexo">carbon</a> which combines glassy and <a href="/facts/Ceramic/9JKudpqX">ceramic</a> properties with those of <a href="/facts/Graphite/sSf3KMXr">graphite</a>. The most important properties are high thermal stability, high thermal conductivity, hardness (7 <a href="/facts/Mohs_scale_of_mineral_hardness/wXBMcVIm">Mohs</a>), low density, low electrical resistance, low friction, extreme resistance to chemical attack, and impermeability to gases and liquids. Glassy carbon is widely used as an electrode material in <a href="/facts/Electrochemistry/C0RUWpBH">electrochemistry</a>, for high-temperature <a href="/facts/Crucible/o7WrIqhu">crucibles</a>, and as a component of some prosthetic devices. It can be fabricated in different shapes, sizes and sections.
The names glassy carbon and vitreous carbon have been registered as trademarks, and <a href="/facts/IUPAC/2AV6myCK">IUPAC</a> does not recommend their use as technical terms.
A historical review of glassy carbon was published in 2021.
