using colloid adsorption method, taking the ferrous oxide nanometer granule to load at the magnesium aluminium sharp crystal stone carrier, adding trace of interim metal oxide assistant, can make the nio, v_2o_5 contained and loaded type super-fine iron base chromium free high temperature shift catalyst.

采用胶体吸附法，将氧化铁纳米颗粒负载于镁铝尖晶石载体上，加入少量过渡金属氧化物助剂，制成含NiO、V2O5负载型超细铁基无铬高变催化剂。

while with higher current desity or by thermal activation, owing to violent movement of li~+ ions, part of crystal structure transforms into rock type similar to face& centered cubic structure of ferrous oxide.

当以较大电流密度嵌锂或热激活时，由于Li~+的运动加剧，部分晶体结构转变为类似于氧化亚铁的面心立方结构。

sometimes they'd also add ferrous oxide to the mix.

the results show that the impurity of ferrous oxide has almost no effect on the oxidation rate of the trivalent chromium.

结果表明：铬铁矿中杂质铁对Cr（Ⅲ）的氧化率无明显影响。

the content of ferrous oxide of slag decreases rapidly due to reduction by h2 and the slag composition approaches that of final slag rapidly, thus the slag in bosh is easy to melt and has good fluidity. quick;

在炉腹区域，氢气具有很强的还原能力，渣中FeO含量迅速减少，但同时炉渣成分快速接近终渣成分，使炉腹渣仍具有较好的熔化性和流动性。

it was found that ferrous oxide with particle size less than 40 nm could be prepared by controlling a certain process conditions.
