摘要:
A semiconductive ceramic composition capable of permitting its resistance-temperature characteristics and resistance to be controlled as desired and a firing temperature of the composition to be lowered to a degree sufficient to facilitate the mass-production at a low cost. The composition contains a main component consisting of SrO, PbO and TiO.sub.2 and is subjected to firing in an oxidizing atmosphere. The composition may contain at least one of SiO.sub.2 and M as a minor component. A variation in amount of the main and minor components permits characteristics and properties of the composition to be varied as desired.

The present invention provides an electrode for a ceramic electrode fluorescent discharge lamp; an electrode material for a discharge lamp, which has high electron flow density, high thermal shock resistance, and reduced deterioration due to sputtering; and also a method for manufacturing the same. The invention makes it possible to reduce the tube diameter of the ceramic electrode fluorescent discharge lamp. An electrode material for a discharge lamp is obtained from a first component of 0.5 to 1.5 mols of BaO, CaO or SrO, a second component of 0.05 to less than 0.3 mols or more than 0.7 to 0.95 mols of ZrO2 or TiO2, and a third component of 0.025 to less than 0.3 mols of V2O5, Nb2O5, Ta2O5, Sc2O3, Y2O3, La2O3, Dy2O3, or Ho2O3, or 0.05 to less than 0.15 mols or more than 0.35 to 0.95 mols of HfO2, CrO3, MoO3 or WO3. This electrode material is granulated and is turned into a massive, granular, or porous electrode material. This is placed in a cylindrical semiconductor ceramic container with a closed bottom and is reduced and fired to prepare an electrode. A mercury dispenser of the ceramic electrode fluorescent discharge lamp is disposed in series between the cylindrical semiconductor ceramic container with a closed bottom and a lead-in portion of the lead wire.

A D-E hysteresis loop of ferroelectrics known in the art has a square shape when the ferroelectrics are a BaTiO.sub.3 single crystal. Such ferroelectrics are used as a non-linear dielectric element of, for example a pulse generating device. The non-linear dielectric element according to the present invention consists of a polycrystal mainly composed of Ba(Ti.sub.0.90-0.98 Sn.sub.0.02-1.00)O.sub.3 and having an average grain diameter of from 10 to 60 .mu.m. The non-linearity is excellent and the temperature dependence of the non-linearity is considerably low.

In multilayer wholly solid lithium ion secondary batteries, a laminate having a collector layer of material with high conductivity superimposed on an active material layer has been disposed so as to attain a lowering of battery impedance. Consequently, in the fabrication of each of positive electrode layer and negative electrode layer, stacking of three layers consisting of an active material layer, a collector layer and an active material layer has been needed, thereby posing the problem of complex processing and high production cost. In the invention, a positive electrode layer and a negative electrode layer are fabricated from paste consisting of active material mixed with conductive substance in a given mixing ratio, and no collector layer is disposed. This realizes process simplification and manufacturing cost reduction without deterioration of battery performance and has also been effective in enhancing of battery performance, such as improvement to cycle characteristics.

The spray drying process and the apparatus therefor, of the present invention use a spray drying chamber formed by a heat-resistant porous membrane. Said porous membrane enables rapid separation of a discharge gas and a produced powder and accordingly total recovery of the produced powder from the spray drying chamber. Therefore, there occurs no nonuniformity in product composition; cleaning and blowing-off of adhered fine powder can be conducted rapidly and easily even in frequent product changes inevitable with a less grade larger quantity production system; as a result, a fine powder of higher quality and higher purity can be produced.

摘要:
Conventional ion rechargeable batteries having an electrode layer on an electrolyte layer suffer from an impurity layer formed at the interface, degrading performance. Conventional batteries with no such impurity layer have a problem of weak interface bonding. In the present invention, in a baking process step after an electrode layer is laminated on an electrolyte layer, materials for an electrode layer and an electrolyte layer are selected such that an intermediate layer formed of a reaction product contributing to charging and discharging reactions is formed at the interface of the electrode layer and the electrolyte layer. In addition, a paste that an active material is mixed with a conductive material at a predetermined mixing ratio is used to form a positive electrode layer and a negative electrode layer. Reductions in electrode resistance and interface resistance and improvement of charging and discharging cycle characteristics are made possible.
