摘要
以钨酸钠为原料、用胶溶法合成了纳米ＷＯ３；比较了四种不同的合成过程，用ＸＲＤ线宽化法与ＴＥＭ对产品表征，粒径平均为４０～６０ｎｍ；讨论了胶体的形成机理．
Nanometric WO3 was synthesized from Na2WO4. 2H2O by colloidal chemistry method. Four different processes were compared with each other XRD line broadening method-and TEM were used for characterization of products. The particles of products have about 40～60 nm in size. The formation mechanism of colloid was discussed.
