Description

TECHNICAL FIELD

[0001] The application relates to the technical field of cesium iodide production, and particularly discloses a crystallization equipment. BACKGROUND

[0002] Cesium iodide is colorless crystal or crystalline powder. It is easy to deliquesce. It is sensitive to light. It is extremely soluble in water, soluble in ethanol, slightly soluble in methanol, and almost insoluble in acetone. The relative density is 4.5. The melting point is 621 DEG C. The boiling point is about 1280 DEG C. The refractive index is 1.7876. It is irritating. Cesium iodide is a colorless crystal or white powder, the density is 4.51 g / cm3, the melting point is 621 DEG C, the boiling point is 1280 DEG C, and it is soluble in water and alcohol. Cesium iodide burns on the flame and has a sky blue flame color. The cesium iodide scintillation crystal can absorb external ray energy to ionize and excite atoms and molecules, and emit fluorescent photons when de-excitation. The density of the crystal is relatively large, and the iodine with high atomic number accounts for 85% of the weight, so the detection efficiency of gamma rays is particularly high, and the relative luminous efficiency is large; the strongest wavelength of the emission spectrum is about 415 nm, which can be well matched with the spectral response of the photomultiplier tube. In addition, the transparency of the crystal is also very good, and the energy resolution when measuring gamma rays is also one of the better scintillators.
