it was shown that the yield value of colloidal silica sol slurry was increased and its suspensibility was improved by adding some additives.
试验结果表明,加入添加剂可提高硅溶胶涂料的屈服值,改善涂料的悬浮性;
homogeneous nanoporous silica films were prepared with colloidal silica sol derived by sol-gel technique of tetraethylorthosilicate(teos) catalyzed with nh3? h2o.
