Antimonic oxide is a chemical compound with the molecular formula Sb2O5. The IPA phonetic transcription for this word is /æn.tɪˈmɒn.ɪk ˈɒk.saɪd/. The first two letters "an" are pronounced with a short "a" sound followed by the "n" sound. "ti" is pronounced with a short "i" sound and "mo" with a long "o" sound. "nic" is pronounced like "nick" and "ox" like "oks". Lastly, "ide" is pronounced with a long "i" sound followed by the "d" sound.
Antimonic oxide is a chemical compound composed of antimony and oxygen, with the chemical formula Sb2O5. It is also commonly referred to as antimony pentoxide. Antimony is a metalloid element with symbol Sb, while oxygen is a non-metallic element with symbol O. Antimonic oxide is a white crystalline solid that exists in various forms, depending on the temperature and method of preparation.
In its structure, antimonic oxide consists of two antimony atoms bonded to five oxygen atoms. The compound is highly insoluble in water but can dissolve in acids. It has a high melting point and sublimes when heated, meaning it transitions directly from a solid to a gaseous state.
Antimonic oxide has several applications in various industries. It acts as a flame retardant, finding use in plastics, rubbers, and textiles. It also serves as a catalyst, aiding in important chemical reactions. Additionally, antimonic oxide is utilized in the manufacture of ceramics, glass, and pigments. Due to its ability to react with other substances, it has been investigated in pharmaceutical research as a potential drug-delivery system.
It is important to note that antimonic oxide is toxic and can cause harmful effects if ingested, inhaled, or absorbed through the skin. Precautions should be taken when handling this compound, including the use of protective equipment such as gloves and masks.

The word "antimonic oxide" has its roots in the elements antimony and oxygen. The term "antimonic" comes from "antimony", which itself derives from the Latin word "antimonium". "Antimony" is believed to have been derived from the Greek words "anti" (against) and "monos" (alone). This may refer to its early use as an alloy or a substance opposing gold in ancient times. The term "oxide" comes from "oxygen", which originated from the Greek words "oxy" (acid) and "gennan" (to be born). Therefore, "antimonic oxide" can be understood as the compound formed when oxygen combines with antimony.
