P-22　In-situ observation of heating behavior of bamboo ash by microscope

Abstract

In this research, in-situ observation during heating of three types of ash es was conducted. The 1^st ash was obtained by carbonizing of bamboo powder at 600°C and 4 hours. The 1^st ash became melting locally at 600°C, and the melting area of it expanded at about 1000°C, and then it melted completely at about 1100°C. On the other hand, the 2^nd ash, which was obtained by bamboo combustion, had higher melting point at about 1000°C than that of the 1^st ash. These results agreed qualitatively with the increase of the melting liquids amount by chemical equilibrium calculation
