Application of TG - DTA to study of Ancient Potteries from Kaveripakkam , Vellore district , Tamilnadu , India
Firing temperature Ancient Potteries are among the oldest and most significant technological innovations in the history of human achievement, and were the first truly synthetic material. Spectroscopic techniques are very useful tools to achieve a detailed knowledge of the art works. In the present study thermogravimetry (TG) and differential thermal analysis was carried out for pottery samples ...
متن کاملMineralogy, Geochemistry and Thermobarometry of Gneisses from Soltanabad Metamorphic Complex (NE Sabzevar)
Soltanabad metamorphic complex cropped out in the ophiolitic range of NE Sabzevar. There is a distinct gneissic body exposed in this complex which is associated with metabasite, serpentinite and adakitic intrusions. Quartz, albite, epidote, amphibole, garnet and chlorite are the rock forming minerals of gneissic samples. Based on abundances of light and dark minerals, different types of felsic,...
متن کاملبررسی روند کاهش وزن مواد منفجره PETN و پنتاستیت به روش های آنالیز حرارتی DTA/TG
In this research, the thermal stability and decomposition kinetics of pentaerythritol tetranitrate (PETN) and Pentastite explosives have been studied experimentally using non-isothermal differential thermal analysis (DTA) and thermo-gravimetric (TG) methods at heating rates of 4.0, 6.0, 8.0 and 10.0 °C/min. The kinetic parameter of activation energy (Ea) and critical ignition temperature fo...
متن کاملRa activity distribution of rocks in the Sopron Mts. (West-Hungary)
Radon gas is the largest natural source of human exposure to ionizing radiation and most of that exposure occurs in indoor air. Bedrock geology is an important factor in radon hazard evaluation of an area. The presence of rock types usually rich in uranium can be considered an indication of a potential radon hazard. In this study the average Ra activity concentration of the main rock types (ort...
متن کاملبررسی رفتار گرمایی لیزاردیت‌های طبیعی در فشار اتمسفری، بر اساس تجزیه دستگاهی XRD و DTA-TG
Determination of stability limits, mineralogical changes and thermal reaction of serpentine minerals are very important for the investigation of magmatism, mechanism and depth of plates of subduction. During the subduction process, serpentine (Lizardite) minerals will release their water due to thermal reactions. This dehydration can play an important role in volcanism processes related to ...
