"The presented elaborate deals with study of the surface properties of chosen moulding powders systems and with theoretical intrepretation of gained findings. During the steel making these systems are demanded to provide a wide range of chemical and physical properties. Because of the complexity of these systems, variability of their chemical structure and conception disunity during the making process, the presented study is aimed for the research of chosen oxidic system from the viewpoint of the influence caused by chemical structure and basicity on its surface properties. The experiment itself was realized on a characteristic system of moulding powder with changeable apportionment of SiO2. Gradually, the concentration of this dominant component was increased and the changes of the temperature dependances were observed by the method of a lying drop. In the following phase of the research the oxidic systems with scaled basicity were derived from this system by gradual additions of CaO and SiO2. Using a"@en . . . "P(GA106/09/0370)" .
