【摘要】 对组成点在Al₂O₃-ZrO₂-SiO₂系ZrO₂-A_1.6S连线上的三个熔制试样,依次在1350、1500和1650℃下保温8h进行热处理。高温热处理后试样的EDAX能谱表明:在趋于平衡的条件下,ZrO₂在莫来石中无明显固溶。更多还原

【Abstract】 Three fused samples selected from the components on the ZrO₂-A_2-（?）S line in Al₂O₂-ZrO₂-SiO₂ system were treated at 1350, 1500 and 1650℃ for 8h. In the case of approaching equilibrium, the solid solubility of ZrO₂ in mullite was found to be insignificant as shown by the results of EDAX spectra of the samples treated at high temperatures.更多还原
