The hydrosol was changed into the hydrophobic colloid particles with an anionic surfactant （DBS）,then the hydrophobic particles were transferred into a seleced organic solvent,and resulted in an organosol. After separating the solvent from the organosol, the residualparticles, ultrafine particles of alumina covered with surfactants were prepared through the processes heating treatment. These particles were easily dispersed with transparency in organic solvents and plastics. 透明超微粒子 氧化铝 表面活性剂 trasparent ultrafine particles alumina surfactant TQ133.1 1996-02-01 2021-04-01 2
