Antimony trioxide (III) oxide is a useful catalyst in the production of polyethylene terephthalate (PET plastic) and the vulcanization of rubber. Safety. Antimony trioxide (III) oxide has suspected carcinogenic potential for humans. [11] Its TLV is 0.5 mg/m3, as for most Antimony trioxide compounds.
Antimon (Sb, lat. stibium, verovatno iz arap. إثمد - ismid) element je iz grupe metaloida sa atomskim brojem 51. Rude antimona su: antimonit (Sb 2 S 3) i ulmanit (NiSbS). To je sjajni, sivi metaloid, koji se u prirodi većinom nalazi kao sulfidni mineral stibnit Sb 2 S 3.Jedinjenja antimona bila su poznata još u antička vremena i bila su korišćena za kozmetiku.

Antimony is an important mineral commodity used widely in modern industrialized societies. The element imparts strength, hardness, and corrosion resistance to alloys that are used in many areas of industry, including in lead-acid storage batteries. Antimony's leading use is as a fire retardant in safety equipment and in …
Antimony - Properties, Reactions, Uses: The most stable form of elemental antimony is a brittle silvery solid of high metallic lustre. Electrolytic deposition of antimony under certain conditions produces an unstable amorphous form called "explosive antimony," because, when bent or scratched, it will change in a mildly explosive manner to the more stable …
Exposure to antimony concentrations of 9 mg/m 3 of air will result in eye, skin, and lung irritation. [ 5] Long-term exposure to antimony in smelting plants may result in the formation of antimoniosis, a particular form of pneumoconiosis. [ 6] Chronic exposure will potentiate lung, heart, and gastrointestinal diseases.
Antimón je kemijski element, ki ima v periodnem sistemu simbol Sb in atomsko število 51. Ta polkovina ima štiri alotropne oblike. Najstabilnejša oblika antimona je modro-bela kovina. Rumeni in črni antimon sta nestabilni nekovini. Uporablja se v požarni izolaciji, barvilih, keramiki, enamelih, številnih zlitinah in gumi.

At present, the most common name for the element is Antimonium.However, in his essay on the chemical signs, Jakob Berzelius used for Antimony the symbol Sb (also St), being an abbreviation of Stibium.This became the official symbol, despite the fact that Stibium or its derivations are rarely used in the different languages.

삼산화 안티모니 (Antimony trioxide)는 화학식 Sb 2 O 3 을 갖는 무기 화합물 이다. 가장 중요한 상업용 안티모니 화합물이다. 광물 발렌티나이트 와 세나모나이트를 통해 자연에서 발견된다. [3] 대부분의 이량체 산화물 처럼 Sb 2 O 3 은 가수분해 와 함께 수용액에 녹는다.
안티모니 [Antimony] 규격 및 사양. Discovered in 1450. Antimony is a relatively stable element and is not attacked by dilute acids or alkalis. It is a poor electrical and thermal conductor. Applications of antimony and its alloys include its use as an alloying element for hardening other metals, a bearing material and in batteries.
Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing. However, there are companies in …
Antimony is a semi-metallic chemical element with an atomic number 51 and symbol Sb in the Periodic Table. The Latin name of Antimony is Stibium. It is generally found in two forms namely metallic form and non-metallic form. Antimony compounds are used since ancient times as a component in cosmetics. It is naturally found in Earth's crust in ...

Antimony is a silvery-white metal that is found in the earth's crust. In the environment, antimony metal is found combined with other substances to form antimony compounds that can be found in ores (rocks found in nature with minerals in them). Antimony can exist in two chemical "states" called trivalent or pentavalent.
