How to measure the conductivity of powdered graphite?

Answer:

The conductive effect of graphite powder is an important factor in making conductive products, so it is very important to know the conductivity of graphite powder.Graphite powders have high electrical conductivity. And stone toner conductivity is an important factor in graphite powder conductive products. There are many factors affecting the conductivity of conductive graphite powder, such as the proportion of graphite powder, external pressure, humidity of the environment, humidity and even light.
Voltammetric measurement of resistanceMethods: using precision small range measurement of electricity meter, multimeter resistance or contrast test you can use small bulbs, according to the brightness of his conductivity, if the bulb is more bright, that resistance is lower.
Some other factors for measuring the resistivity of conductive graphite powderConductivity varies with external factors and is sensitive. The early microphones were made with graphite powder, because the vibration of the voice changed the electrical conductivity between the graphite powders and changed the current to produce analog signals. One can imagine that you need to test his electrical conductivity for the experimental environment.
The conductivity of conductive graphite powder was measured by resin methodTo buy some conductive paint resin, add the same amount of conductive graphite powder, and then coated on a board, with digital multimeter to measure its conductivity on the list.
