Antimonyo

Huwag itong ikalito sa antinomya, isang uri ng kabalintunaan.
Tungkol sa elementong kimikal ang artikulo na ito. Para sa bayan sa Utah, tingnan ang Antimony, Utah.

Ang antimony o antimonyo[8] (baryant: antimonya;[9] Kastila: antimonio) ay isang uri ng elementong kimikal na may sagisag na Sb (Latin: stibium, may kahulugang "marka") at atomikong bilang na 51. Bilang isang metaloyd, mayroon itong apat na alotropikong mga anyo o porma. Isang matatag na anyo nito ang metaloyd na kulay asul-puti. Hindi matatatag na mga hindi-metal ang dilaw at itim na mga antimonya. Ginagamit ang antimonya sa hindi-pagtalab ng apoy sa isang bagay, sa mga pintura, sa mga seramika, sa mga enamel, sa malawak na mga sari ng mga aloy, sa elektroniks, at sa goma.
