factory price and high quality graphite carbon crucible

Specifications

Graphite carbon 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.

Our Silicon Carbide Crucible for melting metals and light alloys are manufactured with a mixture, on the basis of graphite, and silicon carbide from which the clay has been eliminated:

1. The thermal conductivity remains stable throughout their usage.

2. Moisture does not affect them at all and, therefore, they should not be preheated or annealed. They always go to the fire as they leave the packing, without any thermal precaution.

3. They resist the sharpest variations in the temperature.

4. Once located in the furnace, in no instance should they be kept on a slow fire. Always take them to the maximum temperature in the shortest possible time.

5. Their shape and sizes do not alter through usage.

6. Special manufacturing processes permit very short terms of delivery

Features:

1. With good self-lubricating property.

2. Excellent conductive properties, Resistance coefficient is 8-12 ohm.

3. High Thermal stability, low coefficient of thermal expansion.

4. Good chemical stability, it is not dissolved in organic or inorganic solution; it is not reacted with any solution of salt and alkali.

5. High thermal resistance, The melting point of graphite is up to 3650°C, No deformation under high temperature.

6. High-purity, low impurities. 

7.  Small metal contamination. 

We can supply the products according to customer's drawings, samples and performance requirement.
