What's the difference between tellurium and tellurize?

Tellurium


Definition:

  • (n.) A rare nonmetallic element, analogous to sulphur and selenium, occasionally found native as a substance of a silver-white metallic luster, but usually combined with metals, as with gold and silver in the mineral sylvanite, with mercury in Coloradoite, etc. Symbol Te. Atomic weight 125.2.

  • (17) Exposure of developing rats to tellurium results in a highly synchronous segmental demyelination of peripheral nerves with sparing of axons; this demyelination is followed closely by a period of rapid remyelination.

Tellurize


Definition:

  • (v. t.) To impregnate with, or to subject to the action of, tellurium; -- chiefly used adjectively in the past participle; as, tellurized ores.

Example Sentences:
