Abstract

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

Abstract

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.

Keywords

Ulexite, dielectric spectroscopy, boron, impedance, temperature.
