Oxide powder

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.

Hafnium boride

Hafnium boride, the molecular formula is B2Hf, and the molecular weight is 200.112. The mixture of hafnium chloride, hydrogen and boron bromide can be prepared by red hot tungsten wire. It does not react with the mixture of concentrated sulfuric acid and potassium sulfate and phosphoric acid at room temperature, but reacts with the mixture of concentrated hydrochloric acid and concentrated nitric acid. Passing a mixture of hafnium chloride, hydrogen and boron bromide through a red hot tungsten wire can produce hafnium boride.Luoyang Trunnano Tech Co., Ltd provide high purity hafnium boride materials.
