1、WIDELY USED: Graphite crucible is commonly used in metal melting, and is widely used in metallurgy, casting, machinery, chemical and other industrial sectors for smelting of alloy tools and melting of non ferrous metals. 2、THERMAL STABILITY: Can be heated and cooled quickly, resistant to strong acid and alkali corrosion, used in gold and silver and other precious metal melting, excellent thermal shock resistance, electrical conductivity as well as thermal conductivity. 3、HIGH HEAT RESISTANCE: Good thermal conductivity and high temperature resistance, small coefficient of thermal expansion in the process of high temperature use, and certain strain resistance to rapid heat and cold. 4、CHEMICAL STABILITY: Graphite crucible has high temperature resistance, good resistance to oxidation and corrosion, and long service life. Strong corrosion resistance to acid and alkaline solutions, with excellent chemical stability. 5、HIGH PURITY: The graphite crucible is made of crystalline graphite, so it retains the original natural graphite with various physical and chemical properties. Special high purity graphite material is used, high strength and high density.
