紅檜及泡桐膨礦土複合碳材之X射線繞射與拉曼光譜特性
Properties of X-ray Diffraction and Raman Spectra of Taiwan Red Cypress-and Fortune Paulownia-Bentonite Composite Carbides
摘要
本研究係探討紅檜及泡桐膨礦土複合碳材，不同的製備條件對其碳收率、厚度收縮率、X 射線繞射特性及拉曼光譜特性等性質之影響。紅檜及泡桐膨礦土複合材於燒結溫度500℃－700℃ 時之碳收率，隨燒結溫度增加而急速減低，在800℃－1300℃ 時其碳收率會緩和降低。而於1400℃－1600℃ 間則又會急速降低。又複合碳材之厚度收縮率會隨膨礦土含量增加而減低。當燒結溫度1000℃ 時，紅檜及泡桐膨礦土複合碳材之厚度收縮率分別為為8.1%－24.1%與1.82%－25.39%。X 射線繞射圖譜顯示，複合碳材晶體002 面之繞射角度（2θ）在26°左右，而紅檜及泡桐膨礦土複合碳材於燒結溫度為800oC 至1200℃ 時，其層間距離d_(002) 值分別為0.334－0.337nm、0.335－0.337nm。紅檜及泡桐膨礦土複合碳材之拉曼圖譜顯示，其G/D 值隨木質和膨礦土之重量比（W_W /W_B）與燒結溫度增加而有增大之趨勢。

The main purpose of this study was to investigate the properties of the yield, thickness shrinkage, X-ray diffraction and Raman spectra of Taiwan red cypress- and fortune paulownia-bentonite composite carbides under different manufacture conditions. The yields of Taiwan red cypress- and fortune paulownia-bentonite composite carbides decreased rapidly with increasing sintering temperature from 500℃ to 600℃, and decreased slowly from 700℃ to 1300℃, but decreased rapidly from 1400℃ to 1600℃. The thickness shrinkage ratio of Taiwan red cypress- and fortune paulownia-bentonite composite carbides decreased with increasing bentonite ratios, and were 8.1%－24.1% and 1.82%－25.39% at 1000℃ respectively. The X-ray diffraction angle (2θ, d_(002)) of Taiwan red cypress- and fortune paulownia-bentonite composites carbides were nearly 26°, and the interlayer spacing (d_(002)) were 0.334－0.337 nm and 0.335－0.337 nm respectively when sintering temperature were from 800℃ to 1200℃. The G/D intensity ratio of Taiwan red cypress and Fortune paulownia-bentonite composite carbides increased with the increasing of weight ratio (WW /WB) and sintering temperature by Raman spectra.
