titleOfInvention | Quick decision maker of metal mineral powder material conductivity type |
abstract | The invention relates to the technical field of semiconductor minerals, and discloses a device for quickly judging the conductivity type of a metal mineral powder material. When in measurement, K1, K2 and K3 are connected with upper keys, E1, E2, R1 and R2 are adjusted, the current of a working circuit flows into the right side from the left side of K1 and flows out, the current of an excitation circuit flows into the right side from the left side of K2 and flows out, the direction of a magnetic field in the Helmholtz coil is from right to left, and mV1 is measured through a tiny electromotive force measuring circuit; k1 and K2 are connected with a lower key, the current of the working circuit flows into the left side from the right side of K1 and flows out from the left side from the right side of K2, the current of the excitation circuit flows into the left side from the right side of K2, and the mV2 is measured from the left to the right in the direction of the magnetic field in the Helmholtz coil; mV was calculated as (mV1+ mV 2)/2. If mV is positive, the conductivity type is P type, and if mV is negative, the conductivity type is N type. |
