In this paper, differences of the particle size between the pine smoke powders and lampblack powders Coaxial were studied.The results showed that the particle spectrum of the pine smoke powders was unimodal distribution, while it was bimodal for the tung lampblack powders.The average particle size, volume of lampblack powders were about 1/3 and 3% of the pine smoke powders, respectively.But the specific surface area of lampblack particles was 5 times more Earring than the pine smoke particles, which revealed the fact that the lampblack powders were more exquisite than the pine smoke powders.
