Structure or specific heat: the thermodynamic perspective
A model for describing glass
Desktop design of new glass compositions
It is already possible to reliably model many properties of glass and to draft them on the computer before needing to carry out the first trial melts. We expect that the systematic application and logical extension of the concept will make it possible for the old time-consuming and cost-intensive trial-and-error method to be largely replaced with the development of glass compositions with the desired new properties. In this case the term “properties” refers not only to various material data such as density and thermal expansion coefficient, but also to complex behavior patterns such as chemical resistance. Using the three-part model, such complex patterns can be opened up with ease. Let us consider, for example, a glass subjected to a corrosive liquid. The problem breaks down into three parts that can be tackled separately:
Basis for a quantitative high temperature reactor technology
In the same way the melting of a glass from a recipe of raw materials can be analyzed by tackling the following problems:
In this way we gain access to the reversible and irreversible energy shares involved in industrial glass melting. As shown for countless industrial batch formulae, the accuracy of today’s modeling is better than 5 percent. The application of the model, as just described, does not necessarily lead to innovative glass compositions, but it does form the basis for a quantitative high temperature reactor technology for the glass melt.
