Experimentální studium reologických vlastností ekologicky šetrných anorganických systémů

Abstract

This bachelor thesis deals with experimental study of rheological properties of environmentally friendly inorganic systems. The theoretical part is focused on rheology and rheological properties, most of this chapter is devoted to viscosity and methods of its measurement. Then, inorganic (especially oxidic) systems, their properties and problems of their use are described. The practical part is devoted to the preparation of own inorganic systems, in which fluoride content is eliminated by choosing suitable substitutes. Fluorides in inorganic systems are used for lowering liquidus temperatures of these systems, however their usage is harmful to the environment. The aim of the thesis is to describe individual inorganic systems based on experimental measurements, including dependence of dynamic viscosity on temperature and chemical composition, and then to compare these systems.
