摘要
以Al2(SO4)3为原料,在pH值为3 5,溶胶浓度为0 3～0 5mol/L,分散剂0 3%,温度为80℃的条件下,胶溶4h,后经5h100～150℃的水热处理,制得平均粒度小于70nm的AlOOH;用TEM、X射线衍射、TGDTA对样品进行了表征,并研究了不同介质、不同pH、不同分散剂用量对分散性能的影响。
Aluminium sulphate was applied as a precursor. At pH=3.5, the amount of dispersant was 0.3 %, the concentration of colloid was 03-05 mol/L, while the colloid was kept at 80 ℃ for 4 hours. The steady colloid obtained was hydrothermally treated at 100-150 ℃ for 5 hours. The scale of the nanoAlOOH prepared is less than 70 nm. The sample was characterized by TEM, Xrays and TGDTA. The dispersion behavior of AlOOH was studied in different media, pH, concentration of dispersant.
