摘要: Abstract Tin dioxide and aluminum powders were ball milled for different time periods. Sn particles embedded in Al 2 O 3 matrix formed through a displacement reaction after milling. However, SnO cores remain within some larger particles, while smaller pure exist. The particle size was found to increase with the milling time, which is attributed thermal effect provided by exothermic during prolonged Melting point depressions observed. melting temperatures of scale linearly inverse sizes. extent observed be slightly than those literature. This ascribed simultaneous presence Sn–Al Sn–SnO interfaces.
