Tungstate (W12(OH)2O386-), sodium (1:6)

Description:

Tungstate, specifically sodium tungstate with the formula Na6[W12(OH)2O36], is a complex inorganic compound that contains tungsten in its highest oxidation state. It typically appears as a white crystalline solid and is soluble in water, making it useful in various applications. The compound features a polyoxometalate structure, characterized by a framework of tungsten-oxygen octahedra, which contributes to its unique chemical properties. Sodium tungstate is often utilized in catalysis, as a precursor for tungsten-based materials, and in the production of tungsten metal. Additionally, it has applications in the fields of ceramics, glass, and as a reagent in analytical chemistry. The compound is generally stable under standard conditions but should be handled with care due to its potential toxicity and environmental impact. Proper safety measures, including the use of personal protective equipment, are recommended when working with this substance.

Sodium polytungstate

CAS: 12141-67-2

Sodium polytungstate is a magnetic resonance contrast agent that is used for diagnostic imaging and for the treatment of hyperphosphatemia. Sodium polytungstate consists of tungsten oxide particles coated with sodium carbonate, which are dispersed in water. The dry weight of this contrast agent depends on the particle size and composition, but can range from 500 to 1000 mg/g. Magnetic resonance spectroscopy (MRS) is a technique that can be used to investigate the chemical species present in a sample. It has been shown that MRS can be used to optimise the process by which sodium polytungstate is produced, as well as its biochemical properties.
