Enhancement of micalex composition for improving its electric insulation characteristics

Abstract

Creation of materials with improved electric insulation properties is an urgent problem, and micalex is one of the promising materials for developing such compositions. Mica is a good insulator and “mica + glass” composition has considerable mechanical strength, therefore, micalex can be considered as a promising construction and electric insulation material. Objectives of the paper: To obtain micalex composition with improved electric insulation characteristics. Task: Studying the mechanism of interaction between components of the “mica + glass + volcanic cinder” composite and nature of changes in the electric insulation characteristics of micalex with addition of volcanic cinder. Objects of studies were samples of composite micalex material with addition of different amounts of volcanic cinder and with different types of mica as filling material. Methods of investigation. Studies were performed using present-day methods of physical and chemical analysis: X-ray phase analysis and infrared spectroscopy technique. Eclectic and physical characteristics were determined using standard procedures. Results of study: Development of micalex of new composition having sufficient mechanical strength and enhanced electric insulation characteristics owing to addition of volcanic cinder.
