Effect of carbonization on the porosity of beechwood

Preparation of porous SiC ceramic with a woodlike microstructure by sol-gel and carbothermal reduction processing

“…The three major components of wood, namely hemicellulose, cellulose and lignin, break down in a stepwise manner at 200-280 C, 260-350 C and 280-500 C, respectively. 31,32 Between 260 C and 400 C almost 80% of the total weight loss occurs which may vary between 40% (lignin) to about 80% (cellulose) due to evolution of H 2 O, CO 2 , and volatile hydrocarbon species from fragmentation reactions of the polyaromatic constituents via the open pore channel system of wood. The carbon template was shown to be easily machined to net shape prior to conversion to a ceramic material.…”

The synthesis and microstructure of morph-genetic TiC/C ceramics

“…Recently, it was reported in the literature [1][2][3][4][5][6][7][8][9][10] that natural materials with special structure like wood, jute, bamboo, rice husks and coconut shells were utilized as a bio-template to produce porous materials. In comparison with artificial synthetic templates, natural materials exhibit a hierarchically built anatomy, developed and optimized in a long-term evolution process, and are considered cheap, abundant, renewable and environmentally conscious.…”

Conversion of wooden structures into porous SiC with shape memory synthesis

“…The major mass loss occurs in the third stage from 250 8C to 500 8C. As reported in the literature [11,34], this can be understood as the decomposition of hemicellulose, cellulose and lignin, which are the prime soft constituents of wood, with respective decomposition temperatures of 280, 340 and 400 8C [35]. This means that wood started degrading at 250 8C.…”
