Product Description

Silicon Carbide Graphite Crucible/gold silver smelting graphite / non-ferrous and noble metals smelting/Jewelry

Product Description

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

Physicochemical Properties of the graphite crucible:

Type of Crucible	Type S	Type D
Carbon Content/%	≥38	≥45
Bulk Density/(g/cm^3)	≥1.70	≥1.85
Apparent Porosity/%	≤29	≤21
Compression Strength/MPa	≥20	≥25
Refractoriness/°C	≥1400	≥1400

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.
