Novel ceramic-metal intercalation compounds useful in the formation of densified ceramic-metal articles are prepared, for instance, by exposing a ceramic to an organometallic compound in a low dielectric solvent. The use of the ceramic-metal compounds in the formation of articles by densification allows achievement of densified compositions having at least one of increased density, hardness, and toughness.

Novel ceramic-metal compounds

Process for the preparation of asymmetrical alkaline earth metal organoborates and organoaluminates represented by the formula I: ##STR1## and asymmetrical alkaline earth metal organoarsenates and organophosphates represented by the formula II: ##STR2## wherein Z is selected from the group consisting of boron and aluminum; X is selected from the group consisting of phosphorus and arsenic; M is an alkaline earth metal; and in which R.sub.1 -R.sub.6 are independently selected from alkyl, aryl, alkaryl, aralkyl, alkenyl, cycloalkyl, and cyano with the proviso that R.sub.1 -R.sub.6 are not all the same.

Process for the preparation of asymmetrical alkaline earth metal

Alkaline earth metal anode cells having an intercalation cathode, a nonaqueous liquid electrolyte comprising (a) an organic solvent, for instance, an ether, an ester, a sulfone, an organic sulfide, an organic sulfate, a tertiary amine, an organic nitrite, and an organic nitrate, and (b) at least one of an electrolytically active alkaline earth metal salt comprising an organometallic alkaline earth metal salt represented by the formula: ##STR1## wherein Z is selected from the group consisting of boron and aluminum; X is selected from the group consisting of phosphorus and arsenic; M is an alkaline earth metal; and in which R.sub.1 -R.sub.6 are radicals independently selected from the following groups: alkyl, aryl, alkaryl, aralkyl, alkenyl, cycloalkyl, allyl, heterocyclic alkyl, and cyano, with the proviso that R.sub.1 -R.sub.6 cannot be all alkyl or all aryl and triarylalkylborate or aluminate anions, and trialkylarylborate or aluminate anions are excluded and M represents an alkaline earth metal.

Alkaline earth metal anode-containing cell having electrolyte of

An electric current producing primary electrochemical cell having an aqueous electrolyte, an alkaline earth metal anode, and a cathode capable of intercalating ions of the anode metal. The cell operates at an ambient temperature of about 20.degree. C. to about 100.degree. C. at a pH of about 1 to about 5 and exists in a dry (unactivated) state until needed. Activation is initiated by the addition of the electrolyte.

High rate and high energy density cell

An electric current producing primary electrochemical cell and a process for producing electric current at an ambient temperature of about 20.degree. C. to about 100.degree. C. in a primary electrochemical cell using a polymer electrolyte which is a solid at a temperature of about 20.degree. C. to about 100.degree. C.

Electrochemical generator utilizing solid polymer-salt complex

An electric current-producing cell having an anode, a cathode, and an electrolyte. The anode contains an alkali metal and/or an alkaline earth metal. The cathode contains a transition metal diboride.
