碳黑（carbon black），又名炭黑，是一種無定形碳。輕、松而極細的黑色粉末，表面積非常大，范圍從10~3000m2/g，是含碳物質（煤、天然氣、重油、燃料油等）在空氣不足的條件下經不完全燃燒或受熱分解而得的產物。比重1.8-2.1。由天然氣制成的稱“氣黑”，由油類制成的稱“燈黑”，由乙炔制成的稱“乙炔黑”。此外還有“槽黑”、“爐黑”。按炭黑性能區分有“補強炭黑”、“導電炭黑”、“耐磨炭黑”等?？勺骱谏?/span>染料，用于制造中國墨、油墨、油漆等，也用于做橡膠的補強劑。
Carbon black, also known as carbon black, is an amorphous carbon. Light, loose and very fine black powder, surface area is large, ranging from 10 to 3000 m2 / g, is a carbon material (coal, natural gas, heavy oil, fuel oil, etc.) under the condition of insufficient air by the incomplete combustion and thermal decomposition products. The proportion of 1.8 2.1. "Gas black" made from natural gas, known as "black" by oil, and "acetylene black" made from acetylene. In addition, there are "slot black" and "furnace black". According to the performance of carbon black, there are "reinforcing carbon black", "conductive carbon black", "wear-resisting carbon black" and so on. It can be used as black dye to make Chinese ink, ink, paint, etc., also used in rubber reinforcing agent.
