本研究只使用稻殼灰作為二氧化矽來源並以水鋁石為氧化鋁來源,在不使用礦化劑的條件下以水熱法製備富鋁紅柱石。
稻殼在攝氏八百度持溫三小時的燃燒後,所殘留的稻殼灰主要成分為二氧化矽;水鋁石可在攝氏五百六十度至六百三十度時直接轉換成氧化鋁。本研究可同時合成氧化鋁與富鋁紅柱石,且合成溫度比其他合成法還要低溫,如果想快速提昇富鋁紅柱石的純度,可考慮添加礦化劑,如氫氧化鈉或氫氟酸以提高反應物的溶解度,或是添加催化劑加快反應速率。
在不考慮添加任何礦化劑或是催化劑的情況下,可以延長反應時間,因為鋁離子的擴散速率快於矽離子,於是鋁離子擴散到二氧化矽的多寡與快慢便影響到了富鋁紅柱石合成的速度與純度,因此反應時間越長,鋁離子擴散到二氧化矽越多,則富鋁紅柱石的合成率便提高。
This study used rice husks as source of silica and diaspore as source of alpha-alumina to synthesize mullite without added any mineralizer. The rice husks (RHs) were burned under 800℃ for 2 hours, the residual rice husk ashes (RHAs) contained mainly silicon dioxide phase. Diaspore transforms directly to alpha-alumina from 560℃ to 630℃. We can synthesize alpha-alumina and mullite at the same time and the reaction temperature is lower than other synthesizing methods. In order to enhance the purity of mullite fastly, we could add mineralizer, for instance, NaOH and HF, to increase the solubility or add catalyst to decrease the activation energy of diaspore and rice husk ashes. Another way is increasing the reaction time to make Al3+ diffusing into SiO2 in plenty because the diffusibility of Al3+ is higher than Si4+.
