The Material of Graphite Crucible:
The material of Graphite Crucible include Fine-grain Graphite, High Pure Graphite, and Isostatic Graphite. We will choose the material to produce the Graphite Crucible based on customer's different application, working temperature, thermal shock property, acid-base property. The physical and chemical index as below:
Item | Unit | Fine-grain Graphite | High pure graphite | Isostatic graphite |
Max Grain Size | Dia | 0.8mm | 325mesh | 5-22um |
Bulk Density | g/cm3 |
1.73-1.76 | 1.68-1.85 | 1.8-1.85 |
Specific Resistance | µΩm | 7.5 | ≤14 | ≤15 |
Bending Strength | Mpa | 11-12.5 | ≥25 | 12.5 |
Compressive Strength | Mpa | 27-34 | ≥50 | 34 |
Thermal Conductivity | W/(m .k) | 150-160 | ≥130 | 160 |
C.T.E.(100-600)ºC | 10-6/ºC | 2.2 | ≤2.5 | 2.1 |
Ash Content | % | 0.09 | ≤0.15 | 0.09 |
How to use
1.The crucibles should be put on the pallets instead of the ground and stored in a dry place with good ventilation.
2. Use the proper base to support the crucibles. Attention! The base should be with a bigger diameter than the crucibles' bottom and with the same material as the crucibles'.
3.Make sure the furnace lining works well .Make sure the crucible and furnaces are concentric.
4. Use pincers to put the metal into crucible carefully
Packed in plywood crates, inner plastic to prevent water and dust, and braced strongly with steel strip fixed outside
