Abstract
William Hyde Wollaston, an English scientist, have developed outstanding powder metallurgical process for malleable platinum in 1804. This have been considered as the beginning of modern powder metallurgy based on science. The process included some key techniques: purification and micronizing powder in refining of crude metal, compressing of powder under high pressure and sintering at high temperature, which are still important even now. Technical advantage of purification and compressing of powder were accomplished besed on chemistry and mechanics, respectively. Malleable platinum over 1.1ton for various uses was produced by Wollaston for fifteen years.
In this paper, the great accomplishment of Wollaston and its historical backdrop are looked back through two Wollaston's papers on malleable platinum, some articles on the relics handed down by Wollaston and history books on platinum.
