Formation kinetics of high-temperature phase sulphoaluminate;

Study of sulfur-fixing characteristics of sulphoaluminate in different atmosphere at high temperature;

Study of high temperature phase of sulphoaluminate for desulfuration;

The study of the effect of calcium in calcium aluminate ore Powder on the product property of aluminum - calcium saltcoagulants;

Study on the preparation of PAC coagulant from bauxite and calcium aluminate;

Study on properties of Portland cement modified with calcium sulphoaluminate;

Testing methods such as chemical analysis, X-ray diffraction and differential scanning calorimetry were used to study the influence of Fe2O3 on the formation of anhydrous calcium sulphoaluminate ( C 4 A 3S ).

The kinds,shapes and quantities of hydration products and the ion concentration in pore solution were investigated during hydration of fly ash or slag portland cement containing calcium sulphoaluminate by differential scanning calorimetry-thermogravimetry analysis,scanning electron microscope and chemical analysis.

Formation and controlling of calcium-aluminates inclusions in bearing steel;

The relationship between calcium activity (α[Ca]) and aluminum content was analyzed by thermodynamic calculation to guarantee inclusions in liquid region after calcium treatment for X80 pipeline steel,and the α[Ca] ranges were determined to obtain liquid calcium-aluminates inclusions.
