摘要： The present application discloses fired diatomite insulating bodies, typically based on diatomite and a binder, e.g. clay or the like, and possibly one or more fillers. The insulating bodies have improved properties with respect to mechanical and dimensional stability and low thermal conductivity at high temperature compared to conventional diatomite insulating bodies. The effects are obtained by reaction of the basic materials with a metals-masking agent, e.g. aluminium dihydrogen phosphate or mono ammonium phosphate.

摘要： An improved LSCF 6428 perovskite material of the type La 12z Sr x+z Co 0.2+a Fe 0.8+b O 3-´ wherein x = 0.4, z = (0 - 0.1), a = (.01 €• 0.04), and b = (0.05 €• 0.15) for use as an SOFC cathode having increased electronic and ionic conductivity. The general formula is similar to the prior art formulae (La 0.6 Sr 0.4 ) 1-z CO 0.2 Fe 0.8 O 3-´ and La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-´ but applies the z term to La and Sr independently as well as reducing the overall content of La. Further, by adding a small amount (a) of extra Co ions, catalytic activity, conductivity, and sinterability are further enhanced. Adding small amounts (b) of Fe and/or Fe and Co moderates the thermal expansion coefficient with no adverse effect on crystal structure or fuel cell performance. Improved sinterability, microstructure, and reduced film cracking result in high power density of fuel cells. An inherently low-cost solid state reaction method is described.

摘要： There is provided a semiconductive ceramic sintered compact that has a conductivity high enough to attain static electricity removal and antistatic purposes and, at the same time, has excellent mechanical properties or stability over time. The semiconductive ceramic sintered compact includes at least a main phase and first and second phases contained in the main phase observed as a result of observation of any face of the sintered compact, the main phase being a ceramic sintered phase containing Al 2 O 3 particles, the first phase being a grain boundary phase including a conductive substance-containing conductive phase and Al 2 O 3 particles, the Al 2 O 3 particles being present in an island-sea form in the conductive phase, the second phase being a grain boundary phase containing a conductive phase having the same composition as the conductive phase in the first phase and having a structure that electrically connects the first phases three-dimensionally to each other.
