What Are The Different Forms And Grades Of Sodium Tungstate Available Commercially?

Sodium tungstate is a chemical compound with the formula Na2WO4. It is commonly available in several different forms and grades, depending on its intended use and level of purity required.

One form is anhydrous sodium tungstate, which is the purest form of the compound and has a white crystalline appearance. Another form is hydrated sodium tungstate, which contains water molecules within its crystal structure and appears as a yellow or white powder.

In terms of grade, sodium tungstate can be categorized as technical grade or high-purity grade. Technical grade sodium tungstate typically contains impurities and is used in a variety of industrial applications, such as catalysts, pigments, and fire retardants. High-purity grade sodium tungstate has a much lower level of impurities and is used in more specialized applications, such as in the production of tungsten metal and alloys, as well as in analytical chemistry and scientific research.

Overall, the specific form and grade of sodium tungstate that is best suited for a particular application will depend on factors such as the required purity level, intended use, and any specific performance requirements.
