摘要: 采用水热法在500 ℃的低温条件下成功地合成了具有负热膨胀系数的 材料ZrW2O8. X射线衍射结果表明, 当加入的盐酸溶液浓度c HCl≥6 mol/L时, 可用水热法合成出多晶前驱体ZrW2O7(OH)2(H2O)2. 运用 热重-差热分析法研究了前驱体ZrW2O7 (OH)2 (H2O) 2 和产物ZrW2O8的热稳定性. 结果表明, 前驱体在较低温度(500 ℃) 下灼烧即可获得产物ZrW2O8. 经X射线衍射和红外光谱分析证明, 所获得的产物为单一立方相ZrW2O8.

Abstract:Negative thermal expansion compound ZrW2O8 was successfully synthesized by hydrothermal method with low temperature heat treatment at 500 ℃. The XRD result showed that the crystalline precursor ZrW2O7 (OH) 2 (H2O) 2 was formed when the concentration of HCl was equal to or greater than 6 mol/L. The thermal stability of the synthesized ZrW2O8 and its precursor ZrW2O7 (OH) 2 (H2O) 2 were studied by thermo-gravimetric analysis (TGA) and differential thermal analysis (DTA), which confirmed ZrW2O8 could be synthesized through sintering the precursor at low temperature of 500 ℃. Powder X-ray diffraction and FT-IR spectroscopy investigations confirmed that the synthesized product is single cubic ZrW2O8 phase.
