Influence of Waste Glass Addition on Thermal Properties of Kaolin and Illite

摘要

Glass is one of the oldest human-made materials, it is produced in many forms and, theoretically, it is a 100 % recyclable material. There are many ways how to successfully recycle waste glass and the reuse of waste glass as an additive for traditional ceramics has also been studied extensively. Illitic clay (80 mass% of illite, 4 mass% of montmorillonite, 4 mass% of orthoclase, and 12 mass% of quartz) and kaolin (92 mass% of kaolinite, 6 mass% of muscovite, and 2 mass% of quartz) with addition of waste glass (car windshield glass) were studied using thermal analyses - differential thermal analysis (DTA), thermogravimetry (TG), and thermodilatometry (DIL). The presence of the waste glass was observable on the DIL and TG curves where an increase of overall shrinkage and a decrease in mass loss with an increasing amount of waste glass was observed, respectively.
