Oxide powder is the chemical compound solid powder contains one oxygen and another element, such as metal oxides, metal oxides are a chemical compound formed between metals, specifically cations such as Na, K, Li, etc., and oxygen. These compounds require at least of two elements, as compounds do, and always contain at least one oxygen, though there can be more than one. These formations tend to be solid, basic and are more dense than their nonmetallic oxide counterparts. Metal oxides typically contain an anion of oxygen in the oxidation state of −2. A great example is iron oxide, more commonly known as rust, it is the result of iron's prolonged exposure to oxygen rich environments. metal oxides can be easily obtained in nature or reacting metal with acid. In order to get high purity metal oxide powder, nano-metallization is necessary.Luoyang Trunnano Tech Co., Ltd provide high purity nano-materials and elementary substance materials, including nano silicon powder, nano diamond powder, nano boron powder, nano graphite powder and other ultrafine metal materials.
