在平板显示玻璃制造中,通常采用铂金作为玻璃液流道。由于铂金通道需要长期在1 400 ℃以上高温工作,会导致其氧化,从而造成铂金损失;此外,玻璃液中水分解产生的H+透过铂金通道壁释放到外部,富集在玻璃液中的O2-会形成一定量的气泡。为保护铂金通道,提高玻璃质量,通过等离子喷涂方法在铂金通道表面喷涂ZrO2-Y2O3涂层。该涂层与铂金通道的结合强度达到50 MPa以上,可减少铂金通道使用温度下氧化损失率约75%。同时,这种涂层与铂金通道包覆耐火材料有良好的高温适应性。

采用水热包覆法和物理共混法分别制备了ZSM-5@t-ZrO2和ZSM-5/t-ZrO2复合催化剂, 并以ZSM-5和t-ZrO2为对比参考, 研究了不同结构催化剂的物化性质和催化性能。在此基础上, 借助漫反射傅里叶变换红外光谱, 考察了反应温度和预硫化操作对ZSM-5@t-ZrO2复合催化剂上甲醇和硫化氢反应分子吸附转化的影响。结果表明, 水热包覆环境修饰了ZSM-5@t-ZrO2复合催化剂的物化性质, 提升了甲醇硫醇化反应的催化性能和抗积碳积硫失活能力。在反应压力1 MPa、反应温度380 ℃、预硫化1 h、N2流量100 mL/min的条件下, 甲醇转化率、甲硫醇选择性及甲硫醇收率分别达到92.02%、90.56%和82.76%。硫化氢分子在ZSM-5@t-ZrO2催化剂的碱位上吸附解离为巯基, 进而攻击甲氧基, 这是甲硫醇合成反应的速率控制步骤。380 ℃的反应温度和预硫化操作有助于构建形成匹配的甲氧基和巯基生成速率, 在提高催化性能的同时还可有效降低积碳积硫形成速率。

Ba0.85Ca0.15(Ti1−xZrx)O3(BCTZ) ceramics with x= 0.05, 0.10, 0.15, 0.20, 0.25, 0.30 were prepared by the solid-state reaction method. Calcination of the powders was carried out at 1100 ∘C for 4 h and the green pellets were sintered at 1400 ∘C for 2 h. X-ray diffraction patterns of the sintered pellets showed tetragonal splitting up to x= 0.10 while the mixture of the rhombohedral/cubic phase appeared at higher ZrO₂ concentrations. Maximum piezoelectric charge constant d33= 510 pC/N and strain (S= 0.103%) were measured for BCT doped by 0.10 mol ZrO₂. Dielectric constant, remnant polarization and saturation polarization also found maxima for this composition. The Curie temperature (TC) of the compositions decreased with increase in ZrO₂ concentration and reached 98 ∘C, 87 ∘C and 36 ∘C at x= 0.05, 0.10, 0.15 mol, respectively. The remaining compositions have TC below the room temperature; therefore, they can be used for subzero/cryogenic applications. The scanning electron microscopy study revealed an increase in grain size with increase in ZrO₂ concentration and confirmed the complete solubility of ZrO₂ in the crystal lattice. Overall, low ZrO₂-doped BCT compositions with high d33 could be suitable for low temperature (<80 ∘C) applications.Ba0.85Ca0.15(Ti1−xZrx)O3(BCTZ) ceramics with x= 0.05, 0.10, 0.15, 0.20, 0.25, 0.30 were prepared by the solid-state reaction method.
