Ammonium metatungstate and ammonium paratungstate have obvious differences in their uses. The following is a detailed comparison of their uses:
Uses of ammonium metatungstate (AMT)
Production of metallic tungsten and alloy steel: Ammonium metatungstate is an important raw material for the manufacture of metallic tungsten and alloy steel.
Fireproof fabrics: It is also used in the field of fireproof fabrics.
Ceramic industry: Ammonium metatungstate is also used in the ceramic industry.
Petrochemical catalysts: Ammonium metatungstate is the main raw material for tungsten-based catalysts in refineries and is used to manufacture various petrochemical catalysts.
Production of tungsten-based alloys and coatings: Ammonium metatungstate is used as a precursor for the production of tungsten-based materials for the production of alloys and coatings with high temperature stability and wear resistance, which are widely used in aerospace, automotive and electronics industries.
Synthetic high-purity tungsten products: Ammonium metatungstate is a reducing agent that can reduce tungsten oxide to metallic tungsten and is used to produce high-purity tungsten products such as tungsten wire, tungsten tube and tungsten rod.
Production of tungsten-based catalysts: Ammonium metatungstate is also used to produce tungsten-based catalysts, which are highly active, selective and stable and are widely used in the production of chemicals, plastics and other materials.
Research and development: Ammonium metatungstate is also used as a starting material for the synthesis of other tungsten compounds and plays an important role in the field of research and development.
Uses of ammonium paratungstate (APT)
Manufacture of tungsten trioxide or blue tungsten oxide: Further converted into metallic tungsten powder, the downstream products of tungsten powder include electric vacuum materials such as tungsten bars and tungsten wires, as well as alloy series such as tungsten carbide and cemented carbide.
Additives in the petrochemical industry: Ammonium paratungstate is also used in the petrochemical industry as an additive.
Electrolyte: Ammonium paratungstate has good heat resistance, light resistance and chemical corrosion resistance, and is suitable as an electrolyte for products such as batteries, capacitors and thermocouples.
Ammonium metatungstate and ammonium paratungstate have different focuses in their uses. Ammonium metatungstate is mainly used to manufacture metallic tungsten, alloy steel, fireproof fabrics, ceramics, petrochemical catalysts, tungsten-based alloys and coatings, high-purity tungsten products, etc., and is also used in the field of research and development. Ammonium paratungstate is mainly used to make tungsten trioxide or blue tungsten oxide, metal tungsten powder, additives in the petrochemical industry, and electrolytes for batteries, capacitors, etc. These different uses reflect their importance and versatility in the fields of industry and technology.
