Graphite crucible has good thermal conductivity and high temperature resistance, the use of high temperature, the thermal expansion coefficient is small, the rapid heat, quenching has a certain anti-strain properties. Right acid, alkaline solution, strong corrosion resistance, with excellent chemical stability. Characteristics of molded graphite 1.Good electric conductivity and high thermal conductivity 2.Low thermal expansion and high resistance to thermal shock. 3.The strength increases at high temperature, and it can withstand over 3000 degrees. 4.Stable chemical property and hard to react 5.Self lubrication 6.Easy to process
