Parameters of 99.9% Nb 40-100nm Niobium Nanoparticle Nano Niobium Powder for Capacitor
The performance of Niobium nanoparticles depends on several factors such as particle size, composition, and surface chemistry. In general, niobium nanoparticles with sizes between 40-100 nm tend to exhibit higher capacitance due to their smaller dimensions and reduced surface area.
The parameter you mentioned is the “capacitance” of a capacitor made with Niobium nanoparticles. The capacitance of a capacitor can be calculated using the formula:
Capacitance = ε0 * (N/d) * S / C
Where ε0 is the dielectric constant of the material used in the capacitor, N is the number of particles per unit volume, d is the diameter of the particles, and S is the surface area of the particles.
For niobium nanoparticles, a good value for the “diameter” (or “radius”) would be around 2-3 nm, which means that the particles have a diameter of about 2-3 micrometers.
For the “surface area” (or “number of particles per unit volume”), it would depend on the specific method used to produce the particles and the conditions under which they were produced. However, typically, niobium nanoparticles with dimensions similar to those found in commercial capacitors will have relatively high surface areas.
To determine the exact capacitance of your Niobium nanoparticle capacitor, you would need to perform experiments using known values for the dielectric constant, number of particles per unit volume, and surface area. These values should then be used in the formula above to calculate the capacitance of the capacitor.
