Abstract

The extensive deposits of talc occurring at Dagotha in Jaipur district, at Ghewaria and Chandpura in Bhilwara district and at Devpura in Udaipur district of Rajasthan have been characterised mineralogically as well as industrially for utilisation in the field of electroceramics. The study includes the examination of general characteristics, chemical, mineralogical and physical behaviour of talc from individual sources to identify and estimate the quality of the mineral as per BIS specification. The fired properties at four different temperatures starting from 1250° to 1400°C at an interval of 50°C with 2 hrs soaking at the peak temperatures were found out so as to get all possible information for utilising the mineral in the body-mix for high-frequency low-loss steatite insulator. Investigations have also been made by judicial incorporation of talc separately in a typical composition of electro-porcelain and then by evaluation of the product at five different temperatures of 1200°, 1250°, 1300°, 1325° and 1350°C with two hours soaking each for physical and electrical properties suitable for use in radio, radar and other electronic devices.
