摘　　要：The technological process of preparation of colloid Sb 2O 5 by oxidation of Sb 2O 3 with hydrogen peroxide using borax as a stabilizer has been investigated. The optimum preparation conditions selected by orthogonal factorization method as follows m (H 2 O)∶ m (Sb 2 O 3 )=7 5∶1, n (H 2 O 2 )∶ n (Sb 2 O 3 )=3∶1, m (Na 2 B 4 O 7 ·10H 2 O)∶ m (Sb 2 O 3 )=1∶10, 95 ℃, 1 5 h. The conversion of Sb 2 O 3 >95%, light transmittance of colloid >85% and the average diameter of Sb 2 O 5 particles was 50 nm. The colloid Sb 2 O 5 prepared was storage stable without coagulation for more than one year.The technological process of preparation of colloid Sb 2O 5 by oxidation of Sb 2O 3 with hydrogen peroxide using borax as a stabilizer has been investigated.
