In Situ Observation of Oxidation of Liquid Droplets of Tin and Melting Behavior of a Tin Particle Covered With a Tin Oxide Layer

摘要

Oxidation of a liquid droplet of tin (Sn) was observed using an in situ specimen heating holder in an oxygen environment. The surface of the Sn liquid droplet was covered with a tin oxide layer, Sn3O4, the thickness of which depended on the oxygen pressure and temperature. Subsequent cooling of the droplet resulted in the formation of a solid Sn particle covered with a Sn3O4 layer. The solid Sn particle was then heated above the melting temperature of Sn, and the melting behavior of Sn was observed. Microsc. Res. Tech. 72:223-231, 2009.
