    摘要： A process for producing potassium hexatitanate fibers having a tunnel structure, which comprises mixing a titanium component represented by the general formula (Ti, M)O.sub.2 where M is metal impurities with a potassium component selected from the group consisting of potassium oxide, potassium compounds capable of forming potassium oxide when heated and a mixture thereof, to obtain a mixture represented by the general formula K.sub.2 O.n(Ti, N)O.sub.2 where n is from 1.5 to 2.5 and M is as defined above; heating the mixture to obtain a melt; forming from the melt a fibrous material having a layered crystalline structure corresponding to potassium dititanate (K.sub.2 O.2TiO.sub.2); leaching a part of K.sub.2 O from the fibrous material; and heating the fibrous material at a temperature of at least 800.degree. C. and lower than the melting point of the fibrous material.

    摘要： Methods for producing ruthenium perovskite represented by a chemical formula LaRuO3, wherein La is lanthanum to which twelve oxygen ions are coordinated, Ru is ruthenium to which six oxygen ions are coordinated, and O is oxygen, which comprises reacting an aqueous mixed metal ion solution containing metal ions of La and Ru with a precipitate-forming liquid in a reaction container to co-precipitate hydroxides of La and Ru, and subjecting the precipitate to a heat treatment. Alternatively, the co-precipitated mass is deposited on a suitable carrier and subsequently heated to form supported LaRuO3. The co-precipitated La and Ru hydroxides can also be directly formed on a carrier by precipitation from a homogenous solution containing La, Ru and urea. This provides a uniform dispersion of co-precipitated hydroxides on a carrier, subsequent heating of which results in formation of supported LaRuO3. The materials thus obtained are to be used as efficient catalysts for certain reactions of environmental importance. These synthesis methods can also be used for the improved synthesis of LaRuO3 for other applications.
