Abstract
The utility model discloses a high temperature table which is applied in laser-micro Roman spectrum measuring. Body and cover of the high temperature table respectively have two shell layers. An air extracting hole is positioned in the cover of the table. A thermal insulation medium is arranged in the body of the table and a platinum crucible is positioned on an electric heater which is interwinded with platinum heating wires. With the structure, temperature gradient in longitudinal direction and transverse direction can be realized. The utility model adopts automatic heating up and controlling system to accurately control temperature. Stable solid/liquid boundary layer comes into being when crystals are heated to melting point. When the boundary layer is connected with inactive gas, samples can be prevented from oxidizing. When the boundary layer is connected with cooling water circulation, surface temperature of the micro high temperature table keeps the same as room temperature. The boundary layer is connected with an air extracting system, thereby crystal window can be prevented from polluted by volatile substance and connecting the boundary layer to laser-micro Roman spectrometer, real time measurement of Roman spectrum of crystal phase, solid or liquid boundary phase and molten bath can be made at the time of high temperature crystal growth to research the structure and the formation mechanism of the crystal phase, the crystal phase, the solid or liquid boundary phase and the molten bath.
