Different Names of Violet Tungsten Oxide

Violet tungsten oxide is powder with unique structure of needle. It is composed of many different components. The components and their quantities are determined by the specific preparation method. Violet tungsten oxide has some alternate names -γ-tungsten oxide, for example.

Generally, naming of substance follows some rules. The same substance may have some different names. Here are the naming rules of violet tungsten oxide as following as:

1. Naming after the color of substance.

There are three oxides of tungsten: yellow tungsten oxide (WO₃), blue tungsten oxide (WO_2.90), and violet tungsten oxide (WO_2.72). These oxides are named after their colors respectively. The naming approach makes people tell different substances by their colors fast. Many chemical elements are also named in this way, such as gold and silver.

2. Naming after the category of substance.

It can be seen that violet tungsten disulfide is named after the category of the substance. As for violet tungsten oxide, it is a kind of oxide of tungsten. This naming approach not only make people understand the properties of violet tungsten oxide easily – because they can refer to other oxides of tungsten like tungsten trioxide and so on – but make people emphasize on the differences between oxides of tungsten. Carbon monoxide and carbon dioxide are also named after the category of substance. It can be seen from their names that they are all oxides of carbon.

3. Naming after the crystal structure of substance.

Violet tungsten oxide can also be called γ-tungsten oxide. And another oxide of tungsten, blue tungsten oxide, can also be called β-tungsten oxide. The naming of these two oxides of tungsten are on basis of their crystal structures. Generally, the Greek alphabet selected reflects the stability of the crystal structure. β-tungsten oxide has more stable crystal structure than γ-tungsten oxide. The naming of alumina also follows this rule. α- alumina is the most stable phase in alumina.
