The results show that the spinel Ni0.5Zn0.5Fe2O4 forms after the combustion of the gel.

结果表明，自燃烧后已形成完整的结晶尖晶石型Ni0.5Zn0.5Fe2O4纳米晶。

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。

In the condition of keeping F、 K、Na content fixed, To improve slag structure and raise slag melting point and viscosity, MgO content is raised and TiO〓 is added. the main content is as follows:(1) Keeping CaO/SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature goes up 106℃, the viscosity goe down at bigger than 1425℃, but difference is little; keeping /SiO〓 fixed, MgO content rises from 10% to 16%, the free running temperature rises 87℃, the viscosity rises too; adding TiO〓 to 5%, the free running temperature goes up 98℃, the viscosity rise a little.(2) Powder crystal x ray diffraction and microscopic analysis shows: increasing MgO content, the cuspidine will decreace or even disappear, the monticellite goes up with MgO content rising, keeping /SiO〓 fixed, Akermanite content goes up, for high melting point minerals appear or go up, the free running temperature of the slag bearing F is raised; Adding TiO〓, high melting point mineral—Perovskite forms, it can making other minerals'crystalling fast, it is the reason that TiO〓 raises the free running temperature of the slag bearing F.

2对测定粘度的冷凝渣所进行的X粉晶衍射及显微分析和鉴定表明，增加MgO含量，渣中枪晶石将减少甚至消失，而钙镁橄榄石则随MgO含量增加而增加，在／SiO〓不变时，黄长石含量也有所增加，高熔点矿物的出现和增加，提高了含氟熔渣的熔化性温度；加入TiO〓熔渣中将形成高熔点矿物-钙钛矿，钙钛矿的形成还促使黄长石的结晶，这是TiO〓提高含氟熔渣熔化性温度的根本原因。

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。

They are important components of many metamorphic and ignious rocks.

工业上应用较多的主要是镁铝尖晶和镁铬尖晶石。

The results show that formation of FeO*Cr2O3 induces wetting in reaction between the liquid ceramics and outer stainless steel pipe. The ceramics structure can be divided into three zones, i.e. pin microlite, columnar and dendritic zone.

试验结果表明：外层钢管与内衬陶瓷间因形成FeO*Cr2O3尖晶石相而产生反应润湿，陶瓷层由隐针状内层、柱状中间层和外层树枝晶组成。

After highly fractionating, this Crrich magma formed massive chromite (i.e., Saertuohai chromite deposit), and the melt moved into the mantle rock, and formed the wormlike intergrowth texture consisting of Crspinel and orthopyroxene.
