The specifications of the nano-molybdenum oxide dispersion can vary according to specific applications and preparation methods. The following are some common specifications for reference:
concentration
The concentration of the nano-molybdenum oxide dispersion can be adjusted according to needs, and is usually expressed by the molybdenum content, for example, 10 mg/ml or 1 wt% (mass percentage), etc. Effective solid content of commercial nano-molybdenum oxide dispersion: 20% (but the imperial examination market needs to be adjusted)
particle size
The average particle size of nanomolybdenum oxide particles can range from several nanometers to tens of nanometers, depending on the preparation method and requirements. Common characterization parameters include average particle size, particle size distribution, etc. (dispersed particle size: ≤40nm(D50))
dispersion
The dispersibility of the nanomolybdenum oxide dispersion refers to the degree of uniform dispersion of the particles in the liquid. Good dispersion performance helps to maintain a stable dispersion state of particles and prevent particle aggregation and precipitation. Dispersibility can be evaluated by observing the transparency of the dispersion, the sedimentation velocity of particles, and the like.
pH value
The pH value of the nanomolybdenum oxide dispersion can be adjusted and controlled according to specific application needs. Changes in pH may have an effect on the stability of the dispersion and the surface charge of the particles. The pH value of nano molybdenum oxide dispersion is generally 7.5
additive
In order to improve dispersion and stability, appropriate dispersants, surfactants or stabilizers are often added to the nanomolybdenum oxide dispersion. These additives help prevent particle aggregation and settling and enhance dispersion properties.
