Compared with the Russian limestone-sintering technique,the consumption of natural mineral resources and energy,and greenhouse gas emissions in soda-sintering technique could be reduced by 65%,63% and 65%,respectively.

Using soda-lime sintering process-alkali leaching process,under the sintering conditions of temperature 1 250℃,time 120 minutes,calcium-silicon ratio 2.

In this paper,we summarize some factors which affect the magnetic properties of sintered iron.

Summary on new process of SO_4~(2-) treatment of caustic soda and soda coproduct;
