This communication, having a review character of the works developed in the frame of the department Science and Engineering of the Oxidic Materials and Nano-Materials, begins with a short remembering of the problems of the oxide glass structure in the middle of the last century. A special attention is given to the concept elaborated by Professor Şerban Solacolu under the name quasicrystalline structure of glass. In the current year, a Nobel Prize was given for a theory with a similar name, elaborated for non-crystalline metallic alloys. In the department were studied the ideas concerning the chemical equilibrium in oxidic melts, which determine at high temperatures, the formation of a nano-heterogeneous structure with a certain aggregates distribution theoretically calculable which may be correlated with some properties of the resulted glass. An important progress was realized when an experimental method was elaborated for determining the basicity of these structural elements with the possibility to estimate their compositions and distribution. The principle of the experimental method is presented. The distribution of the nano-heterogeneous elements offers interesting information concerning the structure of glass and make possible correlations with properties. So is outlined the possibility to follow, even at the industrial level, the influences of some components of technology on the structure and properties of the produced glass.
