Dielektrik Spektroskopi ile Üleksitin Elektriksel Özellikleri

Öz

Bu malzeme araştırma çalışmasında, üleksit pelletler için dielektrik sabitinin frekansa karşı reel ve sanal kısmı, empedans, kayıp faktörü, iletkenliğin reel kısmı ve sanal kısmı gibi elektriksel parametreler sunulmuştur. Elektriksel özellikler dielektrik spektroskopi ile sıcaklığa ve frekansa bağlı olarak incelenmiştir. Üleksitin dielektrik parametre özelliklerinin gerçek ve sanal kısımları, 25-200 ºC sıcaklık aralığında 100 Hz-15 MHz frekans aralığında ölçülmüştür. AC iletkenliğin oda sıcaklığında artan frekansla arttığı, daha yüksek sıcaklıklarda ise artan frekansla azaldığı gözlemlenmiştir.

Electrical Properties of Ulexite by Dielectric Spectroscopy

Öz

In this work of the material investigation, electrical parameters, which are real part and imaginary part of dielectric constant versus frequency, real part and imaginary part of impedance, dissipation factor, and conductivity, in the bulk ulexite pellet is presented. Electrical properties were investigated dependent temperature and frequency with dielectric spectroscopy. Real and imaginary part of dielectric parameter properties of the ulexite were measured at frequencies from 100 Hz to 15MHz in the temperature range of 25 to 200 ºC. It was observed that AC conductivity increased with increasing frequency at room temperature and decreased with increasing frequency at higher temperatures.
