摘要： The invention comprises novel undoped and doped nanometer-scale CeO2 particles as well as a novel semi-batch reactor method for directly synthesizing the novel particles at room temperature. The powders exhibited a surface area of approximately 170 m2/g with a particle size of about 3–5 nm, and are formed of single crystal particles that are of uniform size and shape. The particles' surface area could be decreased down to 5 m2/g, which corresponds to a particle size of 100 nm, by thermal annealing at temperatures up to 1000° C. Control over the particle size, size distribution and state of agglomeration could be achieved through variation of the mixing conditions such as the feeding method, stirrer rate, amount of O2 gas that is bubbled through the reactor, the temperature the reaction is carried out at, as well as heating the final product at temperatures ranging from 150° to 1000° C.
摘要翻译：本发明包括新型未掺杂和掺杂的纳米级CeO 2 N 2颗粒，以及用于在室温下直接合成新型颗粒的新型半间歇反应器方法。粉末表现出约170m 2 / g的粒度约3-5nm的表面积，并由均匀尺寸和形状的单晶颗粒形成。通过在高达1000℃的温度下进行热退火，可将颗粒的表面积降低至5m 2 / g，这对应于100nm的粒度。对于粒度，尺寸分布和附聚状态可以通过改变混合条件来实现，例如进料方法，搅拌器速率，鼓泡通过反应器的O 2 N 2气体的量，进行反应的温度并在150°-1000℃的温度范围内加热最终产品。

摘要： A ceramic membrane element for an oxygen separator is formed from a ceramic material represented by the structure: A1-xA′xB1-yB′yO3-z where A is a lanthanide element; A′ is a suitable lanthanide element dopant; B is selected from the group consisting of titanium, vanadium, chromium, manganese, iron, cobalt, nickel, zinc and mixtures thereof; B′ is copper; x is between 0.4 and 0.8; y is between 0.1 and 0.9; and z is>0 (and determined by stoichiometry). When B includes cobalt in an amount greater than 0.1, the included iron content is less than 0.05. The membrane element selectively transports oxygen ions therethrough at a relatively low temperature, with a flux detected at about 600° C. This enables the oxygen separator to be operated at lower temperatures than convention separators that frequently have operating temperatures in excess of 900° C. Mechanical stability may be enhanced by the addition of a second phase to the ceramic.

摘要： A unitary layered ceramic structure is disclosed which comprises co-sintered layers. The co-sintered structure comprises a sintered central layer of yttria stabilized zirconia ("YSZ") which is about 8 mole percent yttria and having a density of at least about 95% of theoretical, and sintered outer layers of strontium lanthanum manganite ("LSM") having the approximate molecular composition La.sub.0.8 Sr.sub.0.2 MnO.sub.3, having a density from about 50 to about 60% of theoretical, and having interconnected porosity from about 40 to 50% with an interconnected pore diameter from about one micron to about five microns. The sintered central layer is sandwiched by and bonded and sintered to the outer layers and is essentially free of significant amounts of manganese.A process for making the unitary composition-of-matter is also disclosed which involves tape casting a LSM tape and then on top thereof casting a YSZ tape. The process comprises presintering LSM powder at 1250.degree. F., crushing the presintered commercially available LSM powder, forming a slurry with the crushed LSM, a binder and solvent, tape casting the slurry and allowing the slurry to air dry. A mixture of commercially available submicron size particle YSZ powder is milled with a dispersant and solvent to disperse the YSZ particles thereby forming a dispersed YSZ slurry. The YSZ slurry is then tape cast on the dried LSM tape. If desired, a third layer of LSM can be cast on top of the dried YSZ layer. After drying the composite LSM/YSZ and LSM/YSZ/LSM tapes are fired at 1300.degree. C. No migration of manganese into the YSZ layer was observed with scanning electron microscope/edax in the sintered multilayer tape.

摘要： A composition is derived from an addition polymerizable organotitanium polymer which upon exposure to an oxygen plasma or baking in air, is converted to titanium dioxide (titania) or is converted to a mixed, titanium-containing metal oxide. The metal oxide formed in situ imparts etch-resistant action to a patterned photoresist layer. The composition may also be directly deposited and patterned into permanent metal oxide device features by a photolithographic process.

摘要： An electronically conductive interconnect layer for use in a fuel cell or other electrolytic device is formed with sintering additives to permit densification in a monolithic structure with the electrode materials. Additions including an oxide of boron and a eutectic forming composition of Group 2A metal fluorides with Group 3B metal fluorides and Group 2A metal oxides with Group 6B metal oxides lower the required firing temperature of lanthanum chromite to permit densification to in excess of 94% of theoretical density without degradation of electrode material lamina. The monolithic structure is formed by tape casting thin layers of electrode, interconnect and electrolyte materials and sintering the green lamina together under common densification conditions.
