The present invention relates to paste compositions comprising an indium metal powder; and an organic vehicle. The organic vehicle includes one or more C8-C18 fatty acids; a salt formed from a C4-C6 carboxylic acid and a tertiary alkanolamine; a cationic catalyst; a thixotrope; and a diluent.

A sinterable compound may comprise one or more Ga-alkali metal alloys (and/or one or more Hg-alkali metal amalgams) and one or more filler materials (e.g., one or more dielectric materials). To form a dielectric article or other article, the compound may be formed into a desired shape. Raising the temperature of the compound initiates an exothermic reaction of alkali metal and water and causes the filler materials to self-sinter.

Many examples of metals, photocurable resins, organometallic compounds, photoinitiators, and optional additives are disclosed, and methods of making and using the composition are described.

This invention aims at providing a carbon-coated metal powder having few impurities, a narrower particle size distribution, and sintering properties particularly suitable as a conductive powder of a conductive paste for forming internal conductors in a ceramic multilayer electronic component obtained by co-firing multilayered ceramic sheets and internal conductor layers; a conductive paste containing the carbon-coated metal powder; a multilayer electronic component using the conductive paste; and a method for manufacturing the carbon-coated metal powder. The carbon-coated metal powder has specific properties in TMA or ESCA measurements. The carbon-coated metal powder can be obtained by melting and vaporizing a metallic raw material in a reaction vessel, conveying the generated metal vapor into a cooling tube and rapidly cooling the metal vapor by endothermically decomposing a carbon source supplied into the cooling tube, and forming a carbon coating film on metal nuclei surfaces in parallel with generation of the metal nuclei.
