ceramic graphite crucible 1kg
Product Description
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.
8.Multi-function: Can be used in induction graphite crucible furnace
Physicochemical Properties of graphite crucible:
The crucible is an utensil or melting tank vessels that is made of refractory material (such as clay, graphite, quartz or difficult molten metal iron, etc.).
Graphite crucible, with is special advantages and Plasticity, is widely used in the smelting area, e.g. gold smelting, silver smelting, aluminum smelting, cooper smelting, etc.
