Carbon black (Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero.
OPAas, a precursor of carbon black is a form of ,amorphous carbon that can be transformed into nanosized materials-anwith extremely high surface-area-to-volume ratio, electrical conductivity, low cost, porosity, malleability, and good chemical and electrochemical resistivity (Mudimela et al.he ofrom il palm ash was used to produce carbon black nanofillers with a size of 50 to 100 nm via a ball milling process after pyrolysis in a undergoing furnace at 1000 Â°C. CNFs were added tothe alumina at varying weight fractions and sintered at 1400 Â°C for the production of CNF ceramic composites.
