摘要： A method to produce a magnetic barium or strontium ferrite comprising solubilizing an alkaline earth metal compound in an aqueous solution containing about 20 to about 60 weight percent alkali metal hydroxide. The resulting solution is heated to within the range of about 90.degree. to about 130.degree. C and thereafter admixed with a sufficient amount of a soluble iron compound to form a magnetic precipitate. A crystalline, magnetic ferrite is formed by heating the precipitate to within the range of about 800.degree. to about 1500.degree. C.

摘要： An uncoated ceramic anode comprising titanium having a formal valence of +4; titanium having a formal valence of +3; and a dopant which prevents at least a portion of the titanium +3 from converting to titanium +4 when the ceramic anode is at operating cell conditions. The ceramic anode may have an electrically conductive substance enclosed in its interior. The substance serves to transfer electrical energy from a power source to the ceramic member. These anodes are particularly useful when used in molten salt electrolytic cells because they give good electrolytic production rates while demonstrating exceptionally low wear rates.

摘要： This invention provides a process for producing a ceramic body by heating a ceramic material, such as particulate zirconium oxide, to a temperature greater than about 30 percent of the material's melting temperature, but less than said melting temperature, and thereafter applying sufficient isostatic pressure to consolidate the ceramic material into a body having a density of at least 85 percent of the theoretical density of the material.This invention also provides a process for producing superconducting ceramic articles such as those represented by the general formula YBa.sub.2 Cu.sub.3 O.sub.7-x where 0
