Cím:	Wettability of SiC and alumina particles by liquid Bi under liquid Al / István Budai, György Kaptay
Dátum:	2010
Megjegyzések:	In this paper a new experimental method to measure contact angle of liquid metals on solid particles under an immiscible second liquid metal is described. This includes efficient mixing of the three-phase (two immiscible liquid metals with solid dispersed particles) system with subsequent solidification. The micrographs of the cross sections of samples are analyzed for the distribution of the particles between the bulk of the two metals and the interface between them. As an alternative, exact positions of the particles can be measured at the interface between the two solidified metals. These two measured values are used to estimate the contact angle of one liquid metal on the solid particles under another, immiscible metal. As an example, contact angle of liquid Bi on SiC and alumina particles are measured under liquid Al. Liquid Bi was found to wet perfectly (with zero contact angle) alumina particles under liquid Al, while the contact angle on SiC is found to be around 88 degrees. These contact angle data are shown to be relevant to control the stability of liquid metallic emulsions formed between the two immiscible metals stabilized by the solid particles.
