Optimization of Technological Preparation Condition of Colloid Sb2O5 by Using Sodium Borate as Stabilizer
Abstract:
The technological process of preparation of colloid Sb2O5 by oxidation of Sb2O3 with hydrogen peroxide using borax as a stabilizer has been investigated.The optimum preparation conditions selected by orthogonal factorization method as follows m(H2O):m(Sb2O3)=7.5:1,n(H2O2):n(Sb2O3)=3:1,m(Na2B4O7·10H2O):m(Sb2O3)=11:0,95℃,1.5 h.The conversion of Sb2O3>95%,light transmittance of colloid >85% and the average diameter of Sb2O5 particles was 50 nm.The colloid Sb2O5 prepared was storage stable without coagulation for more than one year.
