The thermal expansion of refractory materials is measured by special  Surface techniques include metrological, mechanical, electric, optical, and laser methods. upon the nature of the sample, the temperature range of the measurement and the resolution  Thermal expansion at high temperatures is associated with physical instability of the sample  Some dilatometers require special treatment of the samples test material (i.e. optical flat, Theoretically, the expansion of the filament sample made of a wire of length l can be The temperature T of the filament sample can be obtained from the change of its 	./cache/work_ro4jk2tefbfw5mc4ruffd7vofm.pdf	./txt/work_ro4jk2tefbfw5mc4ruffd7vofm.txt
