The Fundamental Research on Selenium (I)

Abstract:

In the present investigation, the authors have determinationed some metallographical properties f Se by means of micrography, impact, twisting and corrosion tests. The results obtained are as follows:—
(1) The velocity of nucleation of vitreous Se increases with increasing pressure.
(2) The impact and twisting values increase with increasing temp. up to 120∼125°, which fact corresponds to the change of vitreous Se to metallic one.
(3) The incubation times observed in the corrosion test,decrease in proportion to the lapse of time for heating.
