ZrO_2对镁尖晶石耐火材料力学性能的影响

Influences of ZrO_2 on Mechanical Properties in Magnesia Spinel

在方镁石－尖晶石系统中添加３种含锆氧化物，改变了材料的相组成及显微结构，提高了材料的中温强度和热震稳定性。

Adding three kinds of oxides with ZiO2 in the magnesia spinel system, the composition of phase and the microstructure are changed. The strength of middle temperature and the thermal stability are increased at middle temperature.
