“…Thus, the following processes can occur: dehydration, dehydroxylation, decomposition (transformation of a crystal structure into an amorphous form), recrystallization (once more formation of a crystal structure) [1,3,14,15,17,19]. In the case of the activated bentonite an effect related to the CaCO 3 decomposition can occur [7,10].…”

In this paper, the effects of the examination of the structure of calcium bentonites, activated by sodium carbonate, applied in the foundry industry as a binding agent for moulding sands, subjected to the effects of high temperature, were presented. The examination was conducted with the use of the infrared spectroscopy (FTIR) and X-ray analysis (XRD). In addition, the montmorillonite contents in the bentonite sample was determined with the use of the modern,
Cu(II)-TET complex method and the technological properties of moulding sands containing the examined bentonites, such as: compactability, permeability, compression strength were examined.

This paper presents preliminary research on the possibility of determining the binder content in traditional sandmixes by the microwave method. The research included examinations of three kinds of bentonite. The presented measurements were carried-out with the use of a special stand -the so-called slot line. The concentration of the binder in molding sand was determined on the grounds of measurements of a parameter; i.e., absorbed power or output power of the electromagnetic wave. One of the main advantages of the suggested new method is the short time of the measurement.
