whats the hottest part of a lighter flame
Flame Dicyanoacetylene, a compound of carbon and nitrogen with chemical formula C4N2 burns in oxygen with a bright blue-white flame at a temperature of 5,260 K (4,990 °C; 9,010 °F), and at up to 6,000 K (5,730 °C; 10,340 °F) in ozone.[7] This high flame temperature is partially due to the absence of hydrogen in the fuel (dicyanoacetylene is not a hydrocarbon) thus there is no water among the combustion products.
Fire brick The silica firebricks that line steel-making furnaces are used at temperatures up to 1648°C (3000°F), which would melt many other types of ceramic, and in fact part of the silica firebrick liquefies.[citation needed] High-temperature Reusable Surface Insulation (HRSI), a material with the same composition, was used in the insulating tiles of the Space Shuttle.[citation needed]
