用掃描電鏡(SEM)和傅立葉變換紅外光譜(FT IR)法,研究了淡水蚌殼在不同溫度時(shí)的結(jié)構(gòu)變化。SEM觀察蚌殼縱斷面結(jié)構(gòu)發(fā)現(xiàn),在280℃煅燒10 m in的蚌殼出現(xiàn)了兩條明顯的裂縫,同時(shí)棱柱層和珍珠層微結(jié)構(gòu)發(fā)生變化。FT IR測量蚌殼粉發(fā)現(xiàn),隨著溫度的升高,蚌殼中的有機(jī)物逐漸分解,600℃時(shí)完全消失;同時(shí)無機(jī)物也逐漸分解,在600℃恒定2 h,碳酸鈣完全分解為氧化鈣。

The transformation of framework in freshwater mussel shell was studied by scanning electronic microscope(SEM)and Fourier transform infrared spectroscopy(FTIR) at different temperature.Observation on vertical section of shell through SEM showed there were two cracks in shell at 280 ℃ for 10min and micro fabric of prismatic layer and nacre of having calcined shell transformed.FTIR measuring showed organic compounds gradually decomposed along with increasing temperature and complete vanished at 600 ℃;Inorganic...
