Preliminary Study on Preparation and Characteristics of Ultrafine Bamboo Charcoal Powder

Preparation and characteristics of the ultrafine bamboo charcoal powder were discussed and the preliminary analysis on the properties and structure of the powder was conducted. The results showed that the particle size of the ultrafine bamboo charcoal powder prepared by using highenergy ball milling method was much smaller, the iodine number increased, whereas the electrical resistivity decreased compared to the ordinary bamboo charcal granules.
