Ammonium Metatungstate (AMT) crystals have a series of remarkable characteristics, which are summarized in detail below:
Ammonium Metatungstate Crystal Chemical Formula
(NH₄)₆[H₂W₁₂O₄₀]-xH₂O, in which NH₄ stands for ammonium ions, W stands for elemental tungsten, O stands for elemental oxygen, and x stands for the amount of crystalline water.
Crystal structure of ammonium metatungstate
It consists of tungsten-oxygen octahedra and ammonium oxide ions, which are interconnected by hydrogen bonds to form a stable three-dimensional structure.
Physical Properties of Ammonium Metatungstate Crystals
Appearance of Ammonium Metatungstate Crystals
Usually white or yellowish crystal powder.
Solubility of Ammonium Metatungstate Crystals
Easily soluble in water, but insoluble in ethanol.
Stability of Ammonium Metatungstate Crystals
Stable at room temperature, and has high thermal stability, can withstand high temperature without decomposition.
Chemical Properties of Ammonium Metatungstate Crystals
Oxidizability of Ammonium Metatungstate crystals
Due to the large number of oxygen atoms in Ammonium Metatungstate crystals, it has good oxidizing property, which makes it has important application value in catalytic reaction.
Reducibility of Ammonium Metatungstate Crystals
Ammonium metatungstate is also an effective reducing agent, which helps to reduce tungsten oxide to tungsten metal, which is very important in the production of tungsten-based catalysts.
Ammonium metatungstate crystal purity
Ammonium metatungstate crystals are typically of high purity, with typical impurity levels of less than 0.05%, which is critical for many applications where impurities may affect the performance and quality of the final product.
Ammonium Metatungstate Crystals Applications
Ammonium metatungstate crystals have a wide range of applications in a number of fields, including chemical analysis, atomic absorption spectroscopy, precursors for electrode materials for lithium-ion batteries, catalytic materials, electronic devices, optical materials, and more.
Solubility of Ammonium Metatungstate Crystals
Although the solubility of ammonium metatungstate crystals is low, generally between 0.2% and 0.4%, it can be controlled by adjusting the pH value of the solution, so as to better control the properties of the final product.
In summary, ammonium metatungstate crystals have attracted much attention for their unique chemical formula, physical and chemical properties, high purity, and wide range of applications. These characteristics make ammonium metatungstate crystals play an important role in many industries such as chemistry, electronics, metallurgy, aerospace and so on.
