Small Fire Assay High Temperature Crucible Graphite Crucible For Melting Metal
1. Product description
Graphite crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.
A crucible is a container used to hold metal for melting in a
furnace and it is needed to withstand the extreme temperatures
encountered in melting metals. The crucible material must have a
much higher melting point than that of the metal being melted and
it must have good strength even when white hot.
Graphite crucible can withstand the high temperature, and has good
resistance to chemical erosions and thermal shock. Especially
graphite crucible is ideal for the melting of aluminum, copper and
other metals.
Quartz crucible has the advantages of high purity ,high temperature resistance, with big size ,good thermal insulation, economization on energy ,quality stability etc.
2. Advantages
3.Physical and chemical index
The Graphite crucible have adopted three kinds of materials:Fine-grain Specialty Graphite, High pure graphite, Isostaic graphite.
| Fine-grain Specialty Graphite | High pure graphite | Isostaic graphite | ||
| Item | Unit | Typical value | Typical value | Typical value |
| Max grain size | 0.8mm | ≤325mesh | 5-22vm | |
| Bulk density | g/cm3 | 1.73-1.76 | 1.68-1.85 | 1.8-1.85 |
| Specific resistance | Μ Ω .m | 7.5 | ≤14 | ≤15 |
| Bending strength | M pa | 11-12.5 | ≥25 | 12.5 |
| Compressive strength | M pa | 27-34 | ≥50 | 34 |
| Thermal Conductivity | W/(m .k) | 150-160 | ≥130 | 160 |
| C.T.E.(100-600)℃ | 10-6/℃ | 2.2 | ≤2.5 | 2.1 |
| Ash content | % | 0.09 | ≤0.15 | 0.09 |
4. Applications
Graphite crucible is widely used in all kinds of furnace to melting, such as jewelry, gold, silver, copper, brass, iron, aluminum, zinc, lead and so on.It is widely used in nonferrous metal and precious metal industry, mould industry, glass industry, rare earth industry, photovoltaic industry, laboratory analysis industry and other fields
As long as you provide us with your use, we will choose the suitable crucible for you.
1. According to your application. For example if you need crucible to melt jewelry, gold, silver and other precious metal. We will suggest the high purity graphite for you, because it does not have impurity and will not influence your precious metal.
2. According to your working temperature. For example, if your working temperature is within 500 degree, the ordinary graphite with density 1.75g/cm3 is OK. If your working temperature is more than 2000 degree, I think we must consideration the isostatic graphite with the high density.
3. According to your thermal shock property. For example, in the same temperature 200 degree, the different time will bring different influence.
4. According to your acid-base property. For example, if your working environment is strong acid or strong base, we will suggest impregnation for you.
