Description :
Characteristics : The graphite crucible has good thermal conductivity and high temperature resistance . In high temperature use , the coefficient of thermal expansion is small , and it has certain strain resistance to heat and cooling . It has strong corrosion resistance to acid and alkaline solution and has excellent chemical stability .
High - quality materials : High - purity , high - strength , high - density graphite materials ; processed by high - precision CNC machining . The graphite used is mainly graphite material used for melting precious metals , and the durability is twice that of ordinary materials .
Widily using ： Very versatile , can be used for experiments and smelting of non - ferrous metals . Such as gold , silver , copper , aluminum , lead and so on . Considering the size of this product , it is more suitable for small - capacity metal melting .
Note : It needs to be stored in a dry place . After drying , do not touch the water . Paying attention to slow heating during the first use will help increase the service life .
