2.The process conditions of preparing anhydrous manganese chloride were studied,which adopt manganese-rich slag as the raw material and use hydrochloric acid as the lixiviant.
3.Theoretical Analysis on Controlled Element of Ostwald Ripening Process of Manganese Sulfide in Steels
4.Studies on UV-Vis Spectra of [5,10,15,20]-Substituted Tetrakisphenyl Porphyrin Chlorated Manganese Complexes
5.The calculating results show that the controlled element to be sulfur or manganese is mainly determined by whether (Mn-R·S) being greater than C value-D Mn-γRD S-γ10 5.02-11625/T(D S-γD Mn-γ-1) during the Ostwald ripening process of manganese sulfide in steel; As manganese content in alloy steels containing Mn, low alloy high strength steels and carbon steels is more than 0.7%, the controlled element in steels is sulfur.
6.Fibrous electrolytic manganese dioxide(EMD) was prepared from manganous chloride solution by electrolyzing at 90～95℃with graphite anode, EMD has the exchange properties with cations in aqueous chloride solutions,A lithium type ionic-sieve made from EMD substrate may be used for selective adsorption of trace lithium from sea water with an efficiency of about 90% yield.
7.The results showed that in the presence of nitrate and manganese oxide, 1,2 dechloroethane (1,2 DCA) and vinyl chloride (VC) could be oxidized. The transformation rates of 1,2 DCA under denitrification and manganese reduction were 1 18/h and 0 54/h, respectively, while those of VC were 0 29/h and 0 15/h, respectively.
8.A STUDY OF SPHEROIDIZATION BEHAVIOR OF S.D.NODULARIZER ON CARBICE IN AS-CAST MANGANESE WHITE CAST IRON (PartⅡ)
9.S.D. NODULARIZER SPHEROIDIZATION BEHAVIOR TOWARDS CARBIDE IN AS-CAST MANGANSE WHITE CAST IRON(Part 1)
10.The distribution feature is that in calico purple soil rice and corn are short of zinc,in acid arenaceous soil wheat is short of molybdenum,in gravel yellow soil cole and orange are short of boron,in gles tide soil wheat is short of manganese.
