氧化铝制备

(1)其制备方法有酸法,碱法和醇铝法三种。目前国内主要采用碱法,少数厂家采用醇铝法。
酸法将硫酸铝配成6%的水溶液,加入中和槽中,再将液氨配成15%~20%的氨水,按计算量将氨水快速加入,在强烈搅拌下于室温反应40~60 min,至pH值达到8~9左右时,反应基本完成。将生成的沉淀物经压滤、用无离子水洗涤除去杂质离子,洗涤水中一般加少量氨水调节pH值为8~9,以防洗涤过程中氢氧化铝发生胶凝过程而引起物料损失。将洗涤过的沉淀物加入少量33%的硝酸溶液,在强烈搅拌下生成胶状料浆(此过程称为打浆)。再经喷雾干燥,将得到的微球形氢氧化铝挤条成型,在550℃下焙烧活化4h,即脱水形成活性氧化铝。其

(2)碱法把工业固体烧碱加水配成浓度为600 g/L的烧碱溶液,在50~80℃下加入氢氧化铝后升温至110℃,保温3 h进行反应,将所得溶液用水稀释至含氧化铝为100g/L,静置0.5~1h,经过滤,除去氢氧化铁等不溶性杂质,再将清液和20%硝酸溶液按照一定比例进行中和反应,温度控制在30~50℃下,控制pH 7~7.5,反应10 min 左右以后,再将反应液在常温搅拌下老化2h,经过滤、用无离子水多次洗涤、于110℃烘干、挤条成型、干燥、500℃活化4h,制得活性氧化铝。其

(3)醇铝法将金属铝片加入异丙醇溶液中进行反应,生成异丙醇铝,通过水蒸气鼓泡(入口温度180℃,水解温度175℃),使异丙醇铝水解,生成水合氧化铝,经熟化、过滤、于100℃干燥、500℃脱水活化,制得活性氧化铝。其


(4)高温快脱法:将氢氧化铝(水合氧化铝)经高温快速脱水、成型、水热处理及干燥后制得成品。
(5)炭化铝胶法:将氢氧化铝和氢氧化钠混合,再经中和、二氧化碳碳化、水洗、压滤、干燥、粉碎、捏合、挤条、干燥、煅烧等过程制得成品。
(6)喷雾干燥法:将氢氧化铝与工业硫酸反应,再经碱液中和、水洗、喷雾干燥、煅烧等过程制得成品。
(7)油柱成型法:将铝锭用工业盐酸溶解,再经油柱成球、水洗、干燥、煅烧等过程制得成品。
制备过程中各种条件,特别是沉淀条件对产品的晶型、表面积、孔结构等影响很大,一般地,低温、低 pH 值下易得到无定形氢氧化铝及拟薄水铝石,高 pH 值易生成三水铝石。拟薄水铝石在 430~500℃下,煅烧得到γ-Al2O3,β三水铝石在 300℃煅烧得到 η-Al2O3。

(8)高纯铵明矾热解法以硫酸铝、硫酸铵为原料合成铵明矾(硫酸铝铵),经脱水、热解生成氧化铝,再经转相制得γ-,α-氧化铝。

利用有机铝化合物聚合生成黏稠的聚铝氧烷溶液,将聚铝氧烷溶液进行干式纺丝,得到有机铝化合物纤维,再经煅烧制得氧化铝纤维。

使有机铝化合物聚合,生成黏稠的聚铝氧烷溶液,将其利用普通的干式纺丝法,制成有机铝化合物纤维。再经煅烧制得氧化铝纤维。

9.制法 方法1.用蒸馏水溶解结晶硫酸铝,然后在不断搅拌下慢慢加入硫酸铵溶液,制得硫酸铝铵:

然后加热至100~200℃,除去结晶水后,研成粉末进行高温灼烧,开始在800℃ 灼烧,然后升温至1250~1300℃灼烧4h,冷却后即得氧化铝:
