Beschreibung
Zusammenfassung:	PURPOSE: A crucible for evaporating aluminum, and an evaporation system using thereof are provided to prevent the generation of cracks during a heating process for stably performing the evaporation. CONSTITUTION: A crucible for evaporating aluminum includes a material filler(100) and a material injection unit(200). The material filler has the uniform thickness. The material injection unit is combined to the upper side of the material filler. The injection portion of the material injection unit closely located to the material filler is formed in a narrow shape similar to a bottle neck. The material injection unit has the thickness gradually thickening by the injection direction of materials.
