[Manipulation of gallium restorative materials. 1. Control of wetting action of mixture by mulling with ethanol].
The wetting action of gallium alloy is a handicap when handling the material. Ethanol mulling after mixing was assayed in an attempt to control the wetting action of such mixtures. A mixture of gallium and Ag-Sn-Cu spherical alloy particles was mulled with a small piece of an ethanol-soaked sponge for 10 seconds following mixing by an amalgamator. The effect of this mulling on the adherence of the mixture to the capsules, physical properties and microstructures was determined. Mulling with ethanol effectively controlled the wetting action of the mixture, and reduced adherence to the capsules without affecting physical properties. A decreased reaction phase around the alloy particles was observed in the microstructure of the ethanol-mulled specimen.
