摘要
Using desulfurization lead paste as raw material and phenolic resin as carbon source, lead-carbon composite is prepared through carbonization by high temperature pyrolysis in a tube furnace. Influences of the mass ratio of phenolic resin to desulfurization lead paste, reaction temperature and reaction time are studied. X-ray powder diffractometer is utilized to detect the composition differences of the samples prepared under different conditions; SEM analysis on the samples is carried out by scanning electron microscopy to observe the surface morphology and particle size, and compare the microscopic structure of the samples prepared under different conditions; Backscatter BSEM and EDS spectroscopy are employed to analyze the elemental distribution of samples. The results show that the obtained lead-carbon composite samples have no agglomeration and a uniform distribution of lead carbon when the mass ratio of phenolic resin and desulfurization lead paste is 4:1, reaction has performed at 450℃ for 2.5 h. ? 2020, China National Chemical Information Center.
