The XPS results showed that in one special sample a small portion of Zn~2+ may occupied the spinel crystal of B sublattice.

通过XPS分析，发现内加磁晶和外加磁场的条件下，可能有一部分的锌进入了尖晶石的B位。

The possible reason is that in shock waves a nonstoichiometric ferromagnetic zinc ferrite is formed, in which the distributions of the cations in the A and B sites of the sublattice are different from that formed in calcination, it has stronger exchange interaction and leads to the increase of the magnetization.

可能的原因是冲击波合成了非化学计量比的铁磁性铁酸锌，改变了尖晶石次晶格中A，B位阳离子的分布而使其具有更强的交换相互作用而导致其磁化强度的增加。

The thermal shock resistance of the brick is expected to improve as a result of bigger bulk density, lower thermal expansion coefficient, phase transformation of fused MgO-ZrO2 eutectic powder, formation of magnesiaalumina spinel and forsterite.

材料性能的变化主要与电熔MgO-ZrO2共晶砂的体积密度大、热膨胀系数小、氧化锆的相变、镁铝尖晶石和镁橄榄石等物相的生成相关。
