【 摘 要 】
SrCO3 crystals with various morphologies were prepared using precipitation method by the reaction of Na2CO3 and SrCl2 in aqueous solution in the presence of isophthalic acid and phthalic acid, respectively, which were used as crystal growth adjusters. When isophthalic acid was used as the adjuster, the major morphologies of SrCO3 were center-bundled and two ends emission growing clusters formed by the self-Assembling of short rod whiskers. While using phthalic acid as the adjuster, flower-like SrCO3 clusters were assembled by needle-shaped whiskers when the concentration was low. But the morphologies changed from flower shape to sphere shape with the increasing amount of phthalic acid. The results indicate that the morphology of SrCO3 may be adjusted by the structure of carboxylic acid.
