Study on the method of determining activity of light-burned magnesia;

Magnesia-Zircon clinkers were synthesized using light-burned magnesia and zircon as starting materials by wet grinding processes in this work.

light magnesia,mag- nesium hydroxide,sodium matasilicate pentahydrate and white car- bon black.

A Research is given out on the Produced material by the method of removing Fe3+?Al3+ in the different conditions of acidity from magnesite, measuring the purity and productivity of the production of light magnesia and introducing the fit technology conditions: on PH=8-9,The purity of light magnesia approaches to 99.

Laboratory deamonification of coking plant waste water with light magnesia reveals:in a two-staged deamonification process,the ratio of weight of bottoms:weight of light magnesia consumed is 1∶5.

Technology of preparation for light magnesium oxide from bischofite;

Using brine as the raw materials,and the excessive ammonium bicarbonate as the precipitating agent,We have prepareda light magnesium oxide.

Using a new circluating activating acid-leaching technology, a new method for preparation of light magnesium oxide and water glass from serpentine is presented.
