platinaten.

Brit.

/ˈplatᵻneɪt/,

/ˈplatᵻnət/, U.S.

/ˈplædəˌneɪt/,

/ˈplædənət/,

/ˈplætnˌeɪt/,

/ˈplætn̩ət/

Origin: Formed within English, by derivation. Etymons: platinum n., -ate suffix¹.

Etymology: < platinum n. + -ate suffix¹. Compare French platinate (1834 or earlier in fluo-platinate). N.E.D.(1907) gives only the pronunciation (plæ·tinĕt) /ˈplætɪnət/.

Chemistry.

A salt containing tetravalent platinum in the anion; esp. a salt containing the [Pt(OH)₆]²⁻ ion.

platinatev.

Brit.

/ˈplatᵻneɪt/, U.S.

/ˈplædəˌneɪt/,

/ˈplætnˌeɪt/

Origin: Formed within English, by derivation. Etymons: platinum n., -ate suffix³.

Etymology: < platinum n. + -ate suffix³. Compare slightly earlier platinated adj., and also earlier platinize v. With platinating n. compare French platinage (1873 in this sense; earlier in sense ‘action of blanching red copper with a mercury amalgam’ (1842)).

Now rare.

transitive. = platinize v. (usually in passive).

1858 C. F. Briggs Story of Telegr. 197 The silver laminæ are of considerable thickness, and securely ‘platinated’ all over—that is, platinum is thrown down upon their surfaces in a compact metallic form, and not merely in the black pulverulent state.

1889 London, Edinb., & Dublin Philos. Mag. 5th Ser. 28 454 The plates were next platinated by a process given in Gore's ‘Electro-metallurgy’ under the name of ‘Roseleur's Process’.
