Abstract [en]

This thesis work describes development of a public thermophysical database for molten oxides. The European Space Agency (ESA) brought up the question “is there adequate enough information about molten steel and molten oxides today?” A survey was brought out which showed a joint opinion that an expansion of the database would be appreciated. The Japanese Aerospace Exploration Agency (JAXA) brought matter into business and started collaborations with various universities and institutes around the world, each collaborator became responsible of measurement of one thermophysical property. Properties investigated were/are viscosity, density, thermal diffusivity and surface/ interfacial tension. As part of the project Jönköping University is kept in charge of viscosity experiments where design of experiment has been carried out and viscosities of seven oxide melts are to be measured. Viscosity measurements in molten metal and molten oxides are to be held in a high temperature furnace capable of temperatures up to 1650 degrees Celsius. A viscometer was purchased for the experiments including standard devices made of steel. The included standard devices have a lower melting point than the temperature during exper-iments and are therefore inappropriate for the purpose. A custom made bob was produced which had to be calibrated into the viscometer to enable correct interpretation of experimental results. To know at which temperatures experiments need to be held melting points for the inves-tigated oxide compositions have been analyzed with different software. Because of software dependent results a final conclusion that a Differen-tial Scanning Calorimeter should be used to determine the melting points of each molten oxide is made.
