Information on the high temperature material properties of refractories are the key for their successful application and for the development of new refractories. Due to the heterogeneous microstructure of refractories many standard methods for high temperature testing of materials are not applicable because the sample volume is too small. At HTL new measuring methods for the high temperature characterization of refractories are developed. These so-called ThermoOptical Measuring (TOM) methods aim at a full characterization of the thermal, mechanical and corrosion behavior of refractories at their operating temperatures. Especially a new measuring device, TOM_wave, is introduced. It measures thermal shock resistance, thermal diffusivity and other high temperature material properties by laser heating of samples in a furnace. In addition, a survey is given on the development of TOM devices for the high temperature investigation of other material properties.
