Pronunciation: [lˈiːd ˈɒksa͡ɪd] (IPA) 
Lead oxide is a chemical compound with the formula PbO. It is typically spelled with the sound /lɛd/ for the word "lead", which is a homonym with the verb "lead" (/liːd/). The second syllable of "oxide" is pronounced with a short /ɪ/ sound. So, the proper pronunciation of "lead oxide" would be /lɛd ˈɑksaɪd/. Lead oxide is commonly used in the manufacturing of batteries, paint, and plastics, among other products.
Lead oxide is a chemical compound composed of lead and oxygen atoms, commonly represented by the molecular formula PbO. It is a type of inorganic compound that exists in various forms, but the most common ones are yellow or reddish-brown powders. During its production, lead metal undergoes oxidation, allowing the combination of lead and oxygen to form lead oxide.
Lead oxide is widely utilized across several industries due to its versatile properties. One of its principal applications is in the manufacturing of lead-acid batteries, where it participates in the electrode reactions. It acts as a cathode material, aiding in the conversion of chemical energy to electrical energy within the battery. Additionally, lead oxide is frequently employed as a pigment in the production of ceramics, glass, and paints, providing vibrant and opaque colors.
Moreover, lead oxide plays a significant role in the glass industry as a glass refining agent, enhancing the clarity and quality of glass products. It is also utilized in the production of lead-based additives for gasoline and other fuels, which help improve fuel performance. Furthermore, lead oxide finds its application in certain types of glazes, enamels, and corrosion-resistant coatings, due to its ability to adhere well to various surfaces and provide protective properties.
Despite its various uses, it is important to note that lead oxide can be toxic if ingested or inhaled. It is crucial to handle and dispose of lead oxide properly, following necessary safety precautions and environmental regulations.
The word "lead" comes from the Old English word "lead", which is derived from the Middle English word "led", and ultimately from the Old English word "lēad", meaning "lead metal". The word "oxide" is derived from the Ancient Greek word "oxydēs", which is a combination of the words "oxys", meaning "acid", and "hûdōr", meaning "water". Together, "lead oxide" refers to the chemical compound composed of the element lead and oxygen.
