The graphite used for the fabrication of graphite crucibles other graphite product. Even less pure graphite mixtures still usually contain a high percentage of graphite, which is often mixed with clay; however the crucible does undergo high purification before being used in a process. Crucibles of any size or material are measured in milliliters and they are always portable and handled with tongs and great care. Most crucibles, unless specifically designed, have a smooth surface and they are all dark grey or black in color.
The most common method of melting metal is the use of induction furnaces. Heater in these furnaces is a graphite crucible, the heating is carried out due to induced currents. Induced induction currents heat only crucible and placed in his metal. Energy costs and the time melting in induction furnaces are very low.
Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and other metals. Quartz crucible has the advantages of high purity ,high temperature resistance, with big size ,good thermal insulation, economization on energy ,quality stability etc.
Graphite crucible has good thermal conductivity and high temperature resistance. Thermal expansion coefficient is small. It has a certain strain resistance to acid and alkaline solution of strong corrosion resistance and excellent chemical stability.It is widely used in metallurgy, casting, mechanical, chemical and other industries.
