Abstract: The method is characterized by using ferrite powder as coagulating and precipitating agent to remove floating impurities in the water. Especially the ferrite powder is premixed with a trivalent metal salt such as aluminium salt and ferric salt, or a synthetic polymer coagulant such as amine and amide polymers to be reformed for use. Used ferrite powder is easily and economically recovered by magnetic separation from the precipitated slurries on the bottom of the purifying tank, and separated floating impurites can be handled by the conventional filtering method. Metal components of ferrite powders do not dissolve since ferrite powders are spinnel structured and so chemically stable.
Abstract translation: 该方法的特点是使用铁氧体粉末作为凝结和沉淀剂去除水中的浮游杂质。 特别地，铁氧体粉末与三价金属盐如铝盐和铁盐或合成聚合物凝结剂如胺和酰胺聚合物预混合以进行改性。 使用的铁氧体粉末通过与净化槽底部的沉淀浆料的磁分离容易且经济地回收，并且可以通过常规的过滤方法来处理分离的浮选浮选。 铁氧体粉末的金属组分不溶解，因为铁氧体粉末是尖晶石结构的并且化学稳定。

Abstract: A silicon thin film anode for a lithium secondary battery is provided to control the volume change generated in charging/discharging effectively, to prevent the delamination phenomenon from a current collector, to improve capacity and cycle property due to excellent electric conductance and adhesion. A silicon thin film anode(1) for a lithium secondary battery comprises current collector(10), anode active material layer(20) and carbon coating layer(40). The current collector comprises metal. The anode active material layer comprises a silicon and is formed on a current collector. The carbon coating layer covers the anode active material layer and does not react with electrolyte.

Abstract: 0.2-50 wt % of Silver compounds such as Ag2O, AgO, AgNO3, AgCl3, AgSO4, Ag were added in manganese oxides such as MnO, MnO2, Mn3O4, Mn2O3, were fine grinded, and added a catalyst binder such as colloidal silica, ethyl silicate or colloidal alumina to give a slurry of the catalyst. Title catalyst useful for a complete combustion of an oil stove was prepared by coating the slurry on the catalyst carrier such as ceramic, metal net, ceramic woven fabrics or ceramic nonwoven fabrics.
Abstract translation: 将0.2-50重量％的银化合物如Ag 2 O，AgO，AgNO 3，AgCl 3，AgSO 4，Ag加入锰氧化物如MnO，MnO 2，Mn 3 O 4，Mn 2 O 3中，进行细磨，并加入催化剂粘合剂如胶体二氧化硅， 硅酸乙酯或胶体氧化铝，得到催化剂浆液。 通过将浆料涂布在诸如陶瓷，金属网，陶瓷织物或陶瓷无纺织物的催化剂载体上来制备用于油炉完全燃烧的标题催化剂。
