Title | Paper, 'Note on the thermo-electric position of platinoid' by James Thomson Bottomley and A [Aikitsu] Tanakadate |
Creator | Tanakadate; Aikitsu (1856-1952); Japanese physicist |
Date | 1889 |
Description | The authors write: 'In carrying out a series of experiments on radiation of heat by solid bodies, an investigation to which one of the present writers has for some time past devoted considerable attention, it became necessary, for a purpose which need not here be detailed, to select a thermo-electric pair of metals, of which one metal is essentially platinum, as it passes through glass. Various pairs were considered, and some trials were made; and it was finally determined to make use of platinum and platinoid. The latter metal is an alloy whose electrical and mechanical properties were investigated some years ago by one of the present writers; and since that time it has assumed considerable importance in the construction of electrical instruments and resistance coils. Partly on this account, and partly from present requirements, it became both interesting and necessary to determine the thermo-electric constants for a specimen of this alloy.'
