【摘要】：在十二烷基苯磺酸鈉(SDBS)的輔助下,利用六水氯化鎂和無水碳酸鈉在2個(gè)階段不同溫度下的反應(yīng)直接合成堿式碳酸鎂微球。利用XRD、SEM等表征方法研究了反應(yīng)溫度、熱解溫度、攪拌速率和攪拌時(shí)間等條件對(duì)產(chǎn)物的影響。結(jié)果表明:反應(yīng)溫度為70℃、熱解溫度為120℃、攪拌時(shí)間為60 s時(shí),可得到球形度高、顆粒均勻、顆粒粒徑約為25μm的堿式碳酸鎂微球。反應(yīng)溫度、熱解溫度、攪拌時(shí)間、攪拌速率均對(duì)球形堿式碳酸鎂的尺寸和微觀形貌起到調(diào)節(jié)作用。
[Abstract]:With the aid of sodium dodecylbenzene sulfonate (SDBS), the basic magnesium carbonate microspheres were synthesized directly by the reaction of magnesium chloride hexahydrate and anhydrous sodium carbonate at different temperatures at two stages. The effects of reaction temperature, pyrolysis temperature, stirring rate and stirring time on the product were studied by XRD,SEM. The results show that when the reaction temperature is 70 鈩，
