Little has been reported on the effects of powder characteristics and processing parameters. In general, large pores provide high permeability but with low capillarity and vice versa. The objective of this study was thus to understand the effect of pore characteristics on the permeability when different powders and different compacting pressures and sintering temperatures were employed. Results show that dendritic powders, when pressed at low pressures and sintered at high temperatures, give the best performance.application/pdf404556 bytesapplication/pdfzh-TW國立臺灣大學材料科學與工程學研究所燒結熱導管銅粉毛細力滲透力散熱heat pipesintered wickspermeabilityreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/12421/1/902216E002043.pdf
