Tetracomponent System State Diagrams for Analysis of Material Compositions
Keywords:state diagrams, materials, compositions, compounds, composites.
Chemical compounds, composites and raw material mixture compositions expressed by system state diagrams were
analysed in this work. The amounts of components % are given, also other parameters (such as temperature, pressure,
etc.) can be included. Generally monocomponent (one material, temperature and pressure coordinates), bicomponent
(two materials, temperature coordinates) and tetracomponent (three materials, also isotherms can be shown) are used. In
this paper, we examined the tetracomponent system state diagram formation, compound or composite composition
inclusion into diagrams and also composition identification possibilities. It is shown that the composition can be
introduced into the diagram also by the method which could be of interest to patent authors, because some of the
information in the diagrams can acquire a “know–how” function.
