Allotropes of carbon Instead they were called zeolite-templated carbons (ZTCs). The name derives from their origin inside the pores of zeolites, crystalline silicon dioxide minerals. Another team recognized them as schwarzites and refined the original synthesis technique. A vapor of carbon-containing molecules is injected into the zeolite, where the carbon gathers on the pores' inner walls. It forms a 2D sheet that pulls inwards, creating the negative curve. Dissolving the zeolite leaves the carbon. Glassy carbon or vitreous carbon is a class of non-graphitizing carbon widely used as an electrode material in electrochemistry, as well as for high-temperature crucibles and as a component
