A solid electrolyte having high electron conductivity and high oxide ion conductivity, which is composed of a sintered body consisting substantially of (a) an oxide of cobalt, (b) an oxide of at least one metal selected from strontium and lanthanum, and (c) an oxide of at least one metal selected from bismuth and cerium. This solid electrolyte is useful for selectively separating oxygen from a gaseous atmosphere having a high oxygen partial pressure into a gaseous atmosphere having a low oxygen ...

A solid lubricant comprising a substantially amorphous carbon micro-sphere selected from carbon micro-beads and carbon micro-balloons having a particle size of 0.1 to 1,000.mu. and a specific gravity of the particle of 0.2 to 2.0, which has excellent low frictional coefficient and wearing resistance.

A solid fuel includes a mixture of a liquid fuel and cyclodextrin or a cyclodextrin - containing decomposition product of starch and a second combustible substance such as pulp.

A solid material which is a transition metal composition, or a support for a transition metal compound, is suspended in a liquid medium, the mixture is subjected to mechanical action and the treated mixture is spray-dried. If the solid is a support material, it is subsequently contacted with a transition metal compound. The mechanical action can be a grinding process or a process providing simultaneous vigorous agitation and a shearing action. The transition metal composition may be used with an...

Solid electrolyte consisting of a ceramic of the aluminum oxide-and-sodium oxide type. The ceramic forming the solid electrolyte has a composition according to the formula ##EQU1## and consists X-ray-wise 100% of a fully stabilized .beta."--Al.sub.2 O.sub.3 phase; wherein A stands for an alkali metal, silver, hydrogen or a hydrogen-containing compound; and M.sup.I and M.sup.II are elements which furnish mono- or bivalent ions; and z.sub.1 and z.sub.2 have values between 0 and 1, and the sum of z...

A lithium-ionic-conductive solid electrolyte consisting of lithium iodide and lithium nitride. It has the feature that the lithium ionic conductivity is higher than in prior-art solid electrolytes, and such feature becomes more remarkable when lithium hydroxide is added.

ZrO.sub.2 -Y.sub.2 O.sub.3 solid electrolytes having a high strength and an excellent deterioration property so as to be durable for a long time, comprised mainly of cubic crystal and monoclinic crystal or cubic crystal, monoclinic crystal and tetragonal crystal, wherein an average grain size of monoclinic crystal or tetragonal crystal is not greater than 2 .mu.m and a ratio of the intensity of the monoclinic (III) X-ray diffraction line to that of the cubic (200) line is 0.01-2.5. In the case o...

This relates to the increasing of the intrinsic viscosity of resins, particularly PET, by effecting a solid state polymerization of the resin. More particularly, the solid stating is effected in conjunction with an injection or extrusion unit wherein after having the IV of the resin increased, the heated resin may be fed dry into an injection unit thereby utilizing the heat of the heated resin to reduce heating cost. The solid state polymerization is effected by heating the resin in the presence...

A solid base with improved properties, such as excellent catalytic performance, is obtainable by reacting alumina with an alkali metal hydroxide in a reaction system at a temperature of 200.degree. to 500.degree. C. to form a reaction product; adding an alkali metal to the reaction system; and reacting the reaction product with the added alkali metal at a temperature of 180.degree. to 350.degree. C., or reacting water-containing alumina with an alkali metal in an amount of 1.01 to 2 times the mo...

A projectile of a predetermined geometrical configuration for small arms ammunition which comprises a solid monolithic body made of a copper alloy of approximately 61.5% of copper, approximately 35% of zinc, approximately 3% of lead and approximately 0.5% of tin.
