High-Purity Molybdenum Trioxide
1. It is used for colorimetric determination of blood glucose, protein, phenol, arsenic, lead, bismuth, etc., and alkaloid testing. Used as reducing agent for phosphorus pentoxide, arsenic trioxide, hydrogen peroxide, phenol and alcohol. It is also used in the preparation of molybdenum salts and molybdenum alloys.
2. It is used as the raw material for the preparation of metal molybdenum and molybdenum compounds. Used as a catalyst in the petroleum industry. It can also be used in enamel, glaze, paint, medicine, etc.
3. This product is an additive flame retardant, which has the dual functions of flame retardant and smoke suppression. It can reduce costs, improve flame retardancy and reduce the amount of smoke when compounded with other flame retardants. Molybdenum trioxide also has the dual effects of flame retardant and smoke suppression, and it shows a certain synergistic effect with aluminum hydroxide trihydrate and antimony oxide.
4. Spectral analysis reagents. Detection of blood sugar, protein, alkaloids, arsenic, phenol. Reducing agent for phosphorus pentoxide, arsenic trioxide and hydrogen peroxide.
5. Molybdenum trioxide is used for electroplating or metal oxide addition in the preparation of molybdate.
