Graphite Crucible
Because the raw material( high pure graphite blocks) are produced by our company,the better quality and lower price can be ensured!
We use pitch coke to produce graphite crucible and blocks, with no petrol coke added, ensuring the high density, high purity, and high strength of our products. Whereas in order to cut the cost, many Chinese companies mix petrol coke with pitch coke to produce graphite rods, reducing the graphite products’ strength and their resistance to oxidation, acid, and alkali. A second differentiator from our competition is that we produce the graphite rods and blocks that we use to manufacture our products, giving us full control of the quality of our product.
| We have two kinds of material of graphite block. |
| Medium material specifications : |
| Density | 1.82-1.85g/cm3 | Ash | 0.01-0.03 |
| Working Temp. | 2000Deg.C | Compressive Strength | >65Mpa |
| Flexural Strength | >32Mpa | Grain Size | 400mesh |
| Electric Resistance | 8-10 μ Ω.m | Carbon content | 99.97-99.99 |
|
Higher material specifications:
| |||||||||||||||||||
| Product Advantages:1. great thermal stability |
| 2 .Great corrosion resistence,impact resistence and acid alkali-resistence. |
| 3 .Great thermal conductivity, which can shorten the melting time and save energy. |
| 4. Less than 300 ppm ash content helps to avoid contaminating the metal. |
| 5 .High purity of graphite reduces the chance of metal sticking to the crucible, making our crucibles last longer. |
