Product details:location : Home > Products > Silicon Carbide Ceramics

Features: 
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.

Note: Other specifications could be customizable.

Applications:

The crucible is suitable for melting such metals as copper, gold, silver, zinc, aluminum, lead, etc. Also represents capacity of molten copper in kiln.

Operate Instruction:

1. Store in dry place to avoid water: slowly roast it to 500 degrees before use.
2. Refill stuff according to the capacity of graphite crucible, avoid to be packed too tight in case the metal thermal expansion burst crucible.
3. It is better to bail out the metal liquid with spoon, avoid using clamp to strength local force and shortening service life.
4. Avoid strong oxidation flame directly sprays into the crucible.
