Temperature and AC electrical properties effects on phosphate natural mixture, Abu Tartur plateau, Western Desert, Egypt

Abstract

Abstract The research is focused on examining electrical properties (conductivity and dielectric constant), mineralogy, and geochemical behaviors of natural phosphate mixtures, Abu Tartur plateau, Western Desert Egypt. Abu Tartur plateau has a rich supply of phosphorus deposits. Phosphate deposits mostly consist of fluorapatite (Ca 5 (PO 4 ) 3 F). Our objective is to evaluate the changes in AC electrical properties, emphasizing the effects of temperature, and frequency variations. Electrical properties expand with temperature due to greater mobility of charge carriers at higher frequencies and at higher temperatures. Electrical characteristics were subjected to a temperature range of 60–700 0 C and frequencies of 42 Hz–5 MHz. Electrical properties of phosphate mixtures have a non-linear association with temperature and are highly dependent on frequency. As temperature rises, the conductivity of the mixture also increases, as evidenced by the temperature coefficient. The completion of these investigations will lead to a greater understanding of the geological and geochemical processes that lead to phosphate formation deposits, as well as the development of more effective industrial methods and material attributes. Temperature and conductivity are connected because dissolved ions increase both temperature and conductivity. Both conductivity and temperature are influenced by dissolved ions, hence they are coupled. Heterogeneity fluctuation can have a significant impact on the electrical characteristics of materials. Due to heterogeneity, the change in electrical characteristics is not monotonically affected by increasing conductor concentration. Presence of electrical features becomes more noticeable as temperature concentration increases. AC electrical conductivity of a phosphate natural combination from Abu Tartur and its fluctuation with temperature is inadequate and this work seeks to close this information gap.
