The graphite crucibles can be divided into two major kinds by the raw material , the first kind is the pure graphite crucibles , with the raw material of the pure graphite blocks and rods , with the different uses and dimensions requirements of the crucibles , we can decide which kind of the graphite material be used , such as the isostatic graphite blocks and rods , moulded graphite blocks and rods , vibracation graphite blocks and rods , extruded graphite blocks and rods . We can aslo make the production and machining of required dimensions and drawings by the customers ; The second kind is the pressed graphite crucibles , it can be divided into the Clay graphite crucibles and the SIC graphite crucibles , in China market the customers always use the Clay graphite crucibles as it is with much lower prices and higher cost performance and for SIC graphite crucibles are widely accepted by the foreign customers with the much longer use life and reliable quality .
Pure Graphite crucibles are most widely usded in the melting of the precious metals , such as the gold , silver and so on . the pressed graphite crucibles can be divided into the crucibles for the use of melting copper and the crucibles for the use of melting aluminum , and also the crucibles that can be used to melting both the copper and aluminum. The advantages of the clay graphite crucibels as The Abnormity -Crucible contains spouted crucible and heightened crucible and thinned crucible. The heightened crucible is applicable in deep chamber and the spouted crucible is applicable in tilting furnace. Large volume and fast heat conduction. The SIC graphite crucibles are with better performance and longer use life. its working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under high pressure. new heat conduction material ensures faster heat conductivity and pollution-free product and reduces adherent slag. high-density body and low apparent porosity greatly improve its heat conductivity. The SIC graphite crucibles is with better anti-corrosion than normal clay-crucible and the advanced process dramatically improves its oxidation resistance, which ensures persistent heat conductivity and long working lifetime. high-density body and logical structure make the product better compression property. The sic graphite crucibles Can be used in induction graphite crucible furnace. Please feel free to contact us for the inquiry or demand of the graphite crucibles.
