摘　　要：用2,3-吡嗪二酸作为配体和碳酸锶反应合成2,3-吡嗪二酸锶配合物([Sr_2(pdc)_2(H_2O)_7]·H_2O,分子式:Sr_2C_(12)H_(20)N_4O_(16),H_2pdc=2,3-吡嗪二酸),以该配合物作为前驱体在不同温度下加热分解合成碳酸锶,分别用X-衍射光谱、红外光谱对碳酸锶分别进行表征,用扫描电子显微镜观察粒子的形貌。结果表明,温度对合成的碳酸锶粒子的形貌有影响。2,3-pyrazine diacid was used as a ligand to synthesize Strontium complex([Sr 2(pdc)2(H 2O)7]·H 2O,formulae:Sr 2C 12 H 20 N 4O 16,H 2pdc=2,3-pyrazine diacid)by reacting between strontium carbonate and 2,3-pyrazine diacid.The complex was used as precursors to synthesize SrCO 3 throung thermally decomposing under different temperatures.The strontium carbonate was characterized by X-ray and IR spectra,respectively,and their morphologies were observed by scanning electron microscopy.The results show that the thermal decomposition temperature can influence on the morphology of SrCO 3.
