Well-crystallized　barium　tungstate　(BaWO4)　Powders　with　different　morphologies　were　successfully　synthesized　via　a　simple　template-free　precipitation　technique.　It　was　found　that　the　selected　reaction　conditions　play　a　different　role　in　controlling　the　morphology　of　the　obtained　powders.　The　variation　of　morphology　of　the　obtained　BaWO4　powder　mainly　depends　on　the　different　reaction　temperature,　PH　value　of　the　starting　solution　and　additive　agents　during　the　precipitation　processing.　Moreover,　the　additive　agent　is　also　a　crucial　factor　on　the　size　of　the　obtained　particles.　A　possible　mechanism　has　been　discussed.　(c)　2005　Elsevier　B.V.　All　rights　reserved.
