The advantages of crucible Crucible is characterized by steady.It can not only resist the high temperature environment ,but also have a function of heat conduction.It is not easy to be out of shape in use procedure and is the proper choice to use under the alternate cooling and heating environment. With stable chemical property, the crucible is hard to be decayed and melted. Even in the low temperature the crucible can also promote the melting of metal materials with no pollution. (1)High Thermal Conductivity: Due to using the high thermal conductivity materials, the melting time is reduced. (2)Thermal Shock Resistance: With strong thermal shock resistance, the crucible is not fragile under the condition of urgent cooling and heating. (3) High Heat Resistance:High refractoriness, resistant to 1200 ~ 1600℃temperature. (4)Erosion Resistance: The resistance to the erosion of melting materials is strong.
