  • 方法三:将有机铝化合物如三烷基铝加水聚合成黏稠的聚合物溶液,再加入烷基硅酸盐和有机溶剂。将其用通常的干式纺丝法制成有机铝化合物纤维。将一次纤维加热无机化,在1000℃的高温下煅烧成氧化铝纤维。 在A12(OH)3 C13?2H2O的水溶液中加入亚微细粒子的α-Al2O3微粉和六水氯化镁,制成黏稠的一次纤维,在纤维表面形成SiO2玻璃涂层,进一步制成氧化铝长纤维。 在铝盐水溶液中加入聚环氧硅氧烧和有机高分子化合物制成黏稠的一次纤维,再加工成δ-A12O3短纤维。
  • 方法一: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 A12(SO4)3+6NH3?H2O→2AI(OH)3↓+3(NH4)2SO4 2AI(OH)3→A12O3+3H2O 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 AI(OH)3+NaOH→NaAIO2+2H2O NaAIO2+HNO3→AI(OH)3+NaNO3 2AI(OH)3[△]→A12O3+3H2O 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 Al+3(CH3)2CHOH→(C3H7O)3AI+H2↑ 2(C3H7O)3AI+4H2O→A12O3?H2O+6C3H7OH A12O3?H2O[△]→A12O3+H2O
