1:Silicon carbide crucibles are generally made of carbon bonded silicon and graphite materials. Silicon carbide crucibles are suitable for smelting and melting precious metals, base metals and other metals in an induction furnace. They are used at a temperature reaching 1600 degree celsius. 

2:The silicon carbide crucible offers a uniform and consistent temperature when melting and has a high strength and resistance to cracking. The uniform temperature gives a high quality molten metal needed for casting long lasting and good quality metal products.

3:Silicon carbide crucibles have good thermal conductivity, high strength, low thermal expansion, oxidation resistance, resistance to thermal shocks, resistance to wetting, high hardness and wear resistance.  

4:Due to the silicon carbide crucible properties, it is applicable in various industries such as, chemical, electron, semiconductor, metallurgy, etc

 

Specifications from the graphite crucible :

1.Long working lifetime: its working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under    high pressure.

2.High thermal conductivity: high-density body and low apparent porosity greatly improve its heat conductivity.

3.New-style materials: new heat conduction material ensures faster heat conductivity and pollution-free product, reduces adherent slag.

4.Resistance to corrosion:better anti-corrosion than normal clay-crucible.

5.Resistance to oxidation: advanced process dramatically improves its oxidation resistance, which ensures persistent heat conductivity and long working lifetime.

6.High-strength: high-density body and logical structure make the product better compression property.

7.Eco-friendly: energy-efficient and pollution-free, not only ensure metal product purity, but also ensure sustainable development on environment.

 

NOTICE: We also supply Copper-melting Clay Graphite Crucible and Aluminum-melting Clay Graphite Crucible. Meanwhile, a matched graphite stand is strongly recommended in order to expand the lifetime and improve heat conduction of crucible.

 

The crucible is  an utensil or melting tank vessels that is made of refractory material (such as clay, graphite, clay, quartz or difficult molten metal iron, etc.).

Graphite crucible, which is divided into general type of graphite crucible, special type of graphite crucible, high purity graphite crucible.Graphite crucible, which is divided into general type of graphite crucible, special type of graphite crucible, high purity graphite crucible.

The main raw materials of Graphite crucible is natural crystalline graphite. Therefore, it maintains the original natural graphite various physical and chemical properties.

Graphite crucible has good thermal conductivity and high temperature resistance;Uder the high temperature, the thermal expansion coefficient is small, rapid heating, quench with certain anti-strain properties. The strong corrosion resistance of acid, alkaline solution has excellent chemical stability.

Graphite crucible, with their more excellent performance, in metallurgy, casting,mechanical, chemical and other industrial sectors, is widely used in smelting and alloy tool steel smelting of non-ferrous metals and their alloys . Besides,it has achieved a good technical and economic results.
