The catalyst stability depends on the extent of stability of the reduced iron to the oxidizing atmosphere.

而且催化剂的稳定性取决于还原态铁对氧化气氛的稳定性。

The results show that the reduction temperature and time have remarkable effect on the metallization rate of reduced iron powder.

研究结果表明，还原温度和还原时间对还原铁粉的金属化率具有显著影响。

The direct reduced iron is a high-quality material after coldly bonding, and the utilizable value of high-purity iron powder is higher.

直接还原铁粉经冷固结成型后即为电炉炼钢的优质原料，而高纯铁粉的利用价值更高。

"And what we found is that a protein called ferroportin that removes iron from cells, that eliminates iron from cells, was markedly reduced in breast cancers when compared to normal breast cells.

Mittal figured he could cut his raw-material costs in half by buying direct-reduced iron rather than scrap.

FORBES: Carnegie would be jealous

The purchase made Ispat one of the world's largest producers of direct-reduced iron, at 7 million tons a year.

FORBES: Carnegie would be jealous

He read about something called direct-reduced iron, a technique for smelting without melting--removing the oxygen from iron ore while it's still solid, that is.
