1. Electrochemical properties (porosity, crystal structure) of electrolytic manganese dioxide (EMD) was found to be evaluated from the potentiometric titration carves obtained for solutions of MNO_3 (M^+ : Li^+, Na^+ and K^+) and Zn (NO_3)_2 with or without EMD powder, and the process of stepwise reduction of the oxide by aqueous hydrazine solution containing MNO_3. A new method for preparation of EMD having excellent characteristics as a positive material for alkaline battery has been developed.2. Factors affecting the codeposition of sparingly soluble particles during electroplating was investigated using acidic copper sulfate and zinc sulfate baths containing alpha-Al_2O_3, TiO_2 and BaSO_4 powders. Such a mechanism on the codeposition that existence of chemically bound CU^<2+> and Zn^<2+> at the particle surface is essential for the particles to be deposited in the metals plated has been proposed.3. Stress corrosion of soda-lime-silica glass was found to depend on both the concentration and the nature of the electrolytes and solution pH. Strong interaction between the glass and divalent cations (especially Zn^<2+>) brought about by chemical reactions resulted in inhibition of stress corrosion of the glass.4. Mullite and ferrite as a complex oxide was surface-chemically investigated in order to apply the results to well difined and controlled preparation of a complex oxide consisting of two kinds of metal oxides.

1.通过对含MnO_3(M^+：Li~(++)，Na~(++)，K~(++))和Zn(NO_3)_2溶液的电位滴定曲线和含MnO_3水溶液的逐步还原过程的研究，评价了电解二氧化锰(EMD)的电化学性质(孔隙率、晶体结构)。在含有α-Al_2O_3、TiO_2和BaSO_4粉末的酸性硫酸铜、锌镀液中，研究了影响电镀过程中难溶微粒共沉积的因素。提出了共沉积的机理，即颗粒表面存在化学结合的Cu^&lt；2+&gt；和Zn^&lt；2+&gt；是颗粒沉积在镀金属中所必需的。钠钙硅玻璃的应力腐蚀与电解液的浓度和性质以及溶液的pH值有关。玻璃与化学反应产生的二价阳离子(特别是Zn~+、Lt；~(2+)、Gt~(2+))之间的强相互作用抑制了玻璃的应力腐蚀。对莫来石和铁氧体作为复合氧化物进行了表面化学研究，以期将研究结果应用于由两种金属氧化物组成的复合氧化物的制备。
