Some Factors Influencing Specific Gravity Determinations on Gold Cast Alloys

Abstract

SYNOPSIS IN INTERLINGUA

CERTE FACTOREs EXERCENTE UN INFLUENTIA SUPER DETERMINATIONES DEL GRAVITATE SPECIFIC IN FUSIONATE ALLIGATOS DE AURO.—Le porositate del fundages reduce le gravitate specific mesurabilemente, e certe processos technic tende a augmentar le porositate. Altere technicas tende a modificar le composition del alligatos, usualmente per reducer le contento de metallo basic e per augmentar le procentage de metallo pretiose. Le fundages esseva prostheses geometric de un peso de circa 4 grammas. Plus grande foramines de fundage resultava in omne casos in productos de plus alte gravitate specific. Nulle alterationes significative in le gravitate specific esseva observate secundo que le fundages esseva facite con o sin reservoir. Varie technicas de fusion e de fundage resultava in alterationes del composition chimic le quales esseva de un magnitude sufficiente pro vitiar le determinationes de gravitate specific.
