DEVICE FOR DETERMINING THE TEMPERATURES FOR PHASE TRANSFORMATIONS

摘要

Use: study of physical and chemical properties of inorganic materials. SUMMARY invented: the device comprises a sealed chamber with a window, placed inside each heater configured dvuhr discharge continuous winding wire made of a material with high resistivity and having a cylindrical shape conjugated with a truncated cone ,,. Inside the heater is placed a crucible fitted on the thermocouple. As the optical microscope system used with two diaphragms induced on the opening of the crucible and the photodiode, which is connected to the output registration system constructed in the form of series-connected differential amplifier and plotter, one input of which is connected to the amplifier, and the other - with a thermocouple. 2 yl.
