Deposition behavior of metal particles with the carbonization of biomass containing metal salts

Abstract

The deposition behavior of metal particles with the carbonization of Sugi wood containing metal salts, such as Cu (NO₃) ₂ and NiCl₂, was studied as the first step of the research in the present work for preparing charcoals with a high thermal conductivity. Sugi wood containing these metal salts was carbonized in an argon gas for 1h at the temperature range from 400 to 1000°C. The charcoals dispersed with metal particles were thus obtained above 400°C. From FE-SEM observations of the obtained charcoals with metal particle, the deposition behavior of Ni particles was found to be different from that of Cu particles.
