Original Abstract

The study of the origin, stability and properties of various calcium silicate polymorphs is important for a better understanding of the processes involved in the production of Portland clinker. At the same time, the synthetic pure clinker phases can serve in further investigations, such as hydration or the effects of plasticisers. The aim of this article is to prepare the pure phase of tetracalcium ferroaluminate and to observe the crystallization process based on the calculation of the size of the crystallite using the simplest method, the Scherrer's equation. Based on the results of the X-Ray analysis, the temperature of 1350 °C with a soaking time of 3 hours is sufficient to produce the tetracalcium ferroaluminate pure phase. This firing mode is also characterized by a very good development of the crystalline structure.

Keywords
